The letter chosen for the fallback site icon was being set
inconsistently throughout the extension. The connect flow was using the
first letter of the `origin` for the letter (which was always `H`,
because `HTTP`), but the connect sites list and the account menu were
using the `name` from the domain metadata.
The `name` is now used for the fallback icon everywhere. A selector
that supplied a default domain metadata object has also been augmented
to use the `hostname` rather than the `origin` as a fallback name, to
match the behavior of the inpage provider.
A new `SiteIcon` component has been created for showing icons
representing web3 sites. The icon has a border and background, and it
has a fallback in case no icon is given. This new component accepts a
`size` prop that controls the size of the icon.
The old `IconWithFallback` component had a hard-coded size in the
SCSS styles for the icon, which was being overridden in a few places.
It was difficult to customize, and overly complicated.
The old `IconWithFallback` component is still used, but it's now
simpler. It only handles rendering the underlying `img` for the icon,
or the fallback letter if no image is given.
A separate `IconBorder` component has been created for the border and
white background used. It's solely used by `SiteIcon` for now, but I
intend to use it elsewhere as well, where this same pattern of a white
background is embedded.

Imported accounts can be removed, but the permissions controller is not
informed when this happens. Permissions are now removed as part of the
account removal process.
Additionally, the `getPermittedIdentitiesForCurrentTab` selector now
filters out any non-existent accounts, in case a render occurs in the
middle of an account removal.
This was resulting in a render crash upon opening the popup on a site
that was connected to the removed account.
Token transfers will now be hidden on the ETH asset page. Arguably
token transfers are still relevant to show on the ETH asset page
because the gas for token transfers is paid in ETH, but they weren't
being displayed in a way that highlighted this (only the token amount
was shown inline - not the gas price).
We will likely restore token transfers to the ETH asset page at a later
date, after designs have been updated to highlight their relevance to
this page.
Editing the name of an account was accidentally made impossible when
FontAwesome was updated in #8256, because the icon we used to use for
the edit button (`fa fa-pencil`) was no longer free. The icon has been
switched to `fas fa-pencil-alt`, which is free.
The list of accounts shown on the first page of the connect flow takes
up the entire height of the window, even if there aren't enough
accounts to fill the space. This looks strange because of the border
around the account list, especially in the case where there are three
accounts in the list.
The list now cedes space to the footer if it can't fill the space
itself. The extra space is taken by whitespace between the footer and
the list.
* restore and enhance the time est feature
background: we had a feature for showing a time estimate on pending txs
that was accidently removed during the redesign implementation. This PR
restores that feature and also enhances it:
1. Displays the time estimate on all views instead of just fullscreen
2. Uses Intl.RelativeTimeFormat to format the time
3. Adds a way to toggle the feature flag.
4. Uses a hook to calculate the time remaining instead of a component

Fiat amounts are now shown inline on token transfers in the transaction
list, where possible (i.e. where the conversion rates are known).
The logic for this hook is pretty tangled because it's used for so many
fundamentally different types of items (eth transactions, token
transactions, signature requests). In the future we should split these
into different components.
The documentation for the `useTokenFiatAmount` hook was updated to make
`tokenAmount` optional, but in practice it already worked as expected
without the amount being passed in.
The asset page component has been split into three parts: the main
asset page wrapper, and a component for the content (either token or
native currency). This makes it easier to add functionality that is
specific to either token asset pages or native currency asset pages.
'Activity' is a better name for this tab because it contains more than
just transactions. Signature requests are also included, and more non-
transaction activity may be included in the future.
initially set out to add the failed tooltip back to the transaction list, but
in the process rediscovered the transaction-status component which illuminated
a fair number of statuses that were not properly handled by the refactor of the
list. These statuses were discussed with UX and engineering team members to come
up with a definitive list of statuses that should be reflected in the UI
Changes:
1. normalized the color of status labels to use Red-500 and Orange-500 where applicable
2. added a new color of icon for pending transactions -- grey
3. added support for dropped and rejected labels
4. failed, dropped, rejected and cancelled all have red icons now.
5. cancelled transactions will reflect a change in the user's balance
6. tooltip displayed for failed transactions
7. Icon logic isolated to a new component.
This hook is responsible for converting a token balance to fiat. It has
been extracted from the `TokenCell` component, and will be used
elsewhere in a future PR.
The conversion of token amounts to fiat amounts was extracted from the
`TokenCell` component, and moved to a utility function. This will be
used elsewhere in an upcoming PR.
The `eth-contracts-metadata` export was mutated in `token-list.js` to
add the token address to the contract metadata, and this was taken
advantage of in the token search component.
Instead, the address is now added to a copy of the token metadata in
the one place it's used. The module export is no longer mutated, and
the unused `defaultTokens` variable in `token-list.js` has been
removed.
The `confirm-approve` page has been converted from a set of container/
component components to a functional component. The `withTokenTracker`
higher-order component has been deleted, as it was replaced by the
`useTokenTracker` hook.
Using flex was getting out of hand, I noticed on develop that when
a pending transaction is coming in the speed up and cancel buttons
cause the icon to center according ot their height as well. A grid
is really what is needed. This seemingly greatly simplifies the CSS
AND html (removes unnecessary nesting of divs)
The entry for imported accounts in the account menu looked wrong with
the new connected site icon - there was no padding between the site
icon and the 'imported' label. The entry was pretty crowded with these
three symbols as well (the third being the 'x' used to remove the
account).
The site icon has been made the right-most icon, so that it lines up
with the site icons shown for other accounts, and spacing has been
added between the site icon and the 'imported' label.
The 'x' used to remove accounts has been removed. Accounts can still be
removed from the 'Account Options' menu on the Home screen. This seemed
like the wrong place for this button to exist, as it's the only action
that can be taken from that menu aside from navigation.
The `TokenBalance` component now uses the new `useTokenTracker` hook
instead of the `withTokenTracker` higher-order component. The component
was converted from a split container/component to a functional
component so that the hook could be used.
The prop `withSymbol` was removed from a few call sites, as it was no
longer used. An empty string was substituted for any falsy `string` or
`symbol` because that's what the `withTokenTracker` higher-order
component did.
The asset list item and transaction list item do not make great use of
screen realestate when in fullscreen mode on larger displays/windows.
This PR adds in a new prop for list-item for displaying content in the
middle of the list-item when on these types of screens. To facilitate
this, some updates were made to styling to allow for the list item to
better control how items are laid out in various breakpoints.
This works makes it possible to display the outdated balance warning
inline in the middle section of the list item, and convert to a tooltip
when on small displays.
The "Connected accounts" modal was throwing an exception when
attempting to render an account that has no `lastActive` time. The
component and related selector has been updated to no longer expect
the `lastActive` time to be set.
Prior to #8653 there was a guarantee that all connected accounts had a
`lastActive` time set, as the time would be set on any account returned
from the `eth_requestAccounts` call. But after #8653 only the primary
account was returned, so only the primary account had a `lastActive`
time set.
Fixes#8733
Each "message" requiring a user confirmation has a unique `type`
property. These `type` properties have all been added as enums, and the
enum is now used wherever the literal string was used previously.
This matches the box shadow on the asset page. Some CSS specificity
hijinks were required to override the base `Tabs` CSS rules, and a new
`tabsClassName` prop was added to the `Tabs` component.
* refactor asset items to use list-item
Refactors the asset-list-item and token-cell to rely on the list-item
component for UI. Little changes were needed to the list-item code
to make this work! The result should be lots of eliminated code

The "the transaction has the expected gas price" test was assuming the
fifth element with the `transaction-breakdown__value` class was the
element with the gas price. In practice that was sometimes not the
case, because some transaction detail fields would not be present, or
would appear after the first render.
The field is now looked up with a test id, ensuring it always finds the
correct field.
The e2e test for the "Hide token" functionality was incorrectly
clicking "Cancel" on the "Hide token" modal, thus not actually testing
that that token was hidden at all.
The "Confirm" button is now selected using a test id, to ensure the
wrong button isn't selected.
The `disabled` prop being passed to the `PageContainer` component in
the render function for the `AddToken` component was a string in some
cases. It should always be a boolean. It has been cast to a boolean in
the one case where it was a string.
A new page has been created for viewing assets. This replaces the old
`selectedToken` state, which previously would augment the home page
to show token-specific information.
The new asset page shows the standard token overview as seen previously
on the home page, plus a history filtered to show just transactions
relevant to that token.
The actions that were available in the old token list menu have been
moved to a "Token Options" menu that mirrors the "Account Options"
menu.
The `selectedTokenAddress` state has been removed, as it is no longer
being used for anything.
`getMetaMetricState` has been renamed to `getBackgroundMetaMetricState`
because its sole purpose is extracting data from the background state
to send metrics from the background. It's not really a selector, but
it was convenient for it to use the same selectors the UI uses to
extract background data, so I left it there for now.
A new Redux store has been added to track state related to browser history.
The most recent "overview" page (i.e. the home page or the asset page) is
currently being tracked, so that actions taken from the asset page can return
the user back to the asset page when the action has finished.
The third and fourth parameters were unused, so they have been removed.
The tests descriptions for both `getToErrorObject` and
`getToWarningObject` have been improved as well.
The chosen token in the `send` flow was set from one of two places:
`metamask.selectedTokenAddress` or `metamask.send.token`. The former is
used most of the time, but the latter is used for the 'Edit' button
shown in the upper-left of the confirmation UI.
The send flow will now exclusively use `metamask.send.token` for the
token state during the send flow. `metamask.selectedTokenAddress` is
now only used for the selected token state on the Home screen. This
simplifies the Redux state, as the send token is now in one place
instead of two, and `metamask.selectedTokenAddress` has only one
purpose.
The `TokenInput` component now takes the token as a prop, instead of
using the `selectedTokenAddress` state. The `UserPreferencedTokenInput`
component that wrapped `TokenInput` has also been updated to take the
token as a prop.
This function primarily ensured that there was a reasonable fallback
for `txParams` if the given transaction was missing it. This fallback
was only used in one place: the customize gas modal, during the send
flow specifically.
The helper function has been removed, and the default `txParams` is set
in the one place it was needed. In the future we should attempt to
simplify this modal so it doesn't need to know details about the
context in which it's being used.
The transaction list now filters by token in the `TransactionList`
component instead of in the transaction selector. This was done in
preparation for the asset page work.
Technically this approach is slightly less efficient than before, as
we're now filtering the transactions after they've been grouped
together rather than beforehand. The difference is minimal though, and
this method is more correct.
The old filtering was broken because it inappropriately filtered out
cancel transactions. Cancel transactions always have the `to` address
set to the same as the `from` address, and the token filter only
returned transactions where the `to` address was set to the token
address.
Now that we're only filtering by the `to` address of the initial
transaction, token transaction groups will be included in their
entirety, including any cancel transactions.
The `decimals` property of tokens was being set as a string instead of
a Number for any tokens added via `getTokenParams`. It's now cast to a
Number instead.
This prop is no longer required, now that the new fullscreen redesign
has been implemented. This was unused before the redesign as well,
seemingly by accident.
The fullscreen UI now shows roughly the same design as the popup UI.
A few additional changes depicted in the new fullscreen designs will
be implemented in subsequent PRs (e.g. the inline buttons on assets)
This was done now to make asset pages easier to implement. Implementing
asset pages solely for the popup UI would have been complicated by the
fact that we use viewport size to switch between the two layouts, so we
would have had to re-route upon resizing the window.
The `AccountDetailsDropdown` component has been rewritten to use the
new `Menu` component, and to follow the latest designs.
This should be functionally equivalent. A couple of the icons have
changed, but that's about it.
Support for a subtitle was added to `MenuItem` to support the `origin`
subtitle used for the explorer link for custom RPC endpoints.
A few adjustments were required to `test/helper.js` to accommodate
the use of `Menu` from a JSDOM context (this is the first time it's
been used in a unit test). A `popover-content` element was added to the
fake DOM, and another global was added that `react-popper` used
internally.
An additional driver method (`clickPoint`) was added to the e2e driver
to allow clicking the background behind the menu to dismiss it. This
wasn't possible using the `clickElement` method, because that method
would refuse to click an obscured element. The only non-obscured
element to click was the menu backdrop, and that didn't work either
because the center was obscured by the menu (Selenium clicks the center
of whichever element is targeted).
The `MenuBar` component has been converted to a functional component.
This was done to make upcoming changes related to the home screen
redesign easier to implement.
The `TransactionViewBalance` component has been split into three
separate components. This was done primarily to make the asset page
easier to implement. Also the name `TransactionViewBalance` didn't
describe this component very well anymore.
Instead of the Ethereum and token-specific logic being in the same
component, the two cases were split into the `EthOverview` and
`TokenOverview` components respectively. They both use the
`WalletOverview` component, which has the structure shared by both
cases.
A `Menu` component has been extracted from the
`ConnectedAccountsListOptions` component. The menu and the menu items
are now the `Menu` and `MenuItem` components respectively.
A custom body was added to the Storybook preview to ensure that the
`popover-content` element was present in the DOM before the Menu was
constructed.
The `Identicon` component was being passed a `network` prop, despite
not accepting a `network` prop.
A duplicate set of `token-cell` tests have also been deleted, as they
used this prop. The tests were never run, because the file was misnamed
(it needs to be named `.test.js`).
CSF = Storybook’s Component Story Format (CSF)
See https://storybook.js.org/docs/formats/component-story-format/
Note that the migrations still use CommonJS require, so the default export as
an object is quite ergonomic (& I don't want to touch the migrations).
This changeset updates the `getOriginOfCurrentTab` selector and the container
for the ConnectedSites page to use `activeTab.origin` instead of parsing the
URL. The `activeTab` URL is parsed in `queryCurrentActiveTab` before the UI is
launched and any subsequent parsing of the URL is unnecessary.
See `queryCurrentActiveTab` in `ui.js:86` [1].

The account options menu is now much faster, and it correctly closes
when 'Switch account' is selected.
A static width had to be set on the menu so that it could be positioned
reliably. Without this width set, it was rendered as a different size
before positioning than after, which resulted in it being positioned
incorrectly. A `z-index` had to be added (equal to the `z-index` used
by the popover component) to ensure it wasn't rendered beneath the
popover.
The menu is automatically positioned relative to the account options
button, appearing below the button by default but above it instead if
there isn't room below. It is positioned to be inside the bounds of the
popover as well.
The account options button is now a `<button>` rather than a `<i>`.
This required a few additional style rules to overrule the default
button styles. Additionally the size was increased so that it matches
the designs more closely.
The callbacks for connecting, disconnecting, and switching accounts
have been updated to use state and props to determine the correct
address to use, rather than being bound to the correct address
parameter in the render function. This means we aren't creating a new
function upon each render anymore.
The `showAccountOptions` method still needs to be bound once per
account, but this was switched to use more readable syntax (`.bind`,
instead of the double arrow function).
`react-popper` and `@popperjs/core` were both added as dependencies.
These should be used for any UI requiring relative positioning (e.g.
tooltips, menus, etc.). Older versions of these libraries are already
in our codebase as transitive dependencies of the tooltip library we're
using.
The connected accounts are now ordered by keyring controller order
whenever the `lastSelected` time is equal. This ensures the order is
identical to what connected sites see. This is especially important
when no accounts have been selected, as it ensures the correct account
is marked as the "Primary" account.
The asset list has been updated to more closely match the new designs.
There are still a few major differences (e.g. the selection state, the
token menu) that can't be implemented until the asset screen has been
implemented.
The background color of the selected asset has been lightened, so that
it's less jarring until we remove it.
What
- modify `ui/app/helpers/utils/transactions.util.js` and
`ui/lib/account-link.js` to strip trailing slashes
if they are present.
- added relevant tests not just for the new scenario,
but also the general scenarios for these functions,
as there previously was no test coverage for these
two functions.
Why
- Current behaviour, when user enters a block explorer URL
when configuring a custom RPC, and that block explorer URL
contains a trailing `/`.
- e.g. `https://block.explorer/`
- this results in a double-slash (`//`) in the transaction
and account URLs generated by MetaMask.
- e.g. `https://block.explorer/tx/0xabcd...`,
`https://block.explorer/account/0xabcd...`
- This needs to be handled using a router redirect
on the server of the block explorer,
and this changes would avoid that requirement.
The tabs on the Home page have been updated to match the new home
screen designs.
A new `activeClassName` prop was added to the `Tab` component to allow
applying different styles to the active tab state.
I ran into specificity problems when overriding the default `Tab` styles
because the import order of our CSS is bizarre and wrong. For now I've
used a crude workaround, but we can fix this properly later by changing
the import order to place styles likely to be overridden first.
All asset list items now use the same component (`AssetListItem`).
Previously the tokens and the Ethereum balance were totally separate
components, despite being styled similarly.
Various unnecessary DOM elements and style rules were removed, but the
overall list looks identical to how it looked before.
`getShowFiatSelector` would return the `showFiatInTestnets` value
directly when on mainnet, which could be `undefined`. Now it is cast to
a Boolean instead.
This was done to fix a PropType warning in a component that will be
included in a future PR, where this selector was used for a required
prop.
Defaults have been added for all three preferences. The default values
added are both falsey, so this shouldn't result in any functional
change. This was done to help make this preferences more easily
discoverable.
The IDs for the `numberOfTokens` and `numberOfAccounts` Action
Dimensions were swapped. These are the correct IDs. We'll have to
consider that these are swapped when viewing any pre-v8.0.0 metrics.
The `.scss` file extension is not required when importing SCSS files.
It has been removed from all imports, for consistency. I chose to
remove it rather than add it everywhere because imports without the
extension seem to be more common.
The CSS class for the fallback Ethereum logo used in the identicon
component was with the `AssetList` styles, and was confusingly named
`balance-icon`. It has been migrated to the identicon styles, and
renamed `identicon__eth-logo`.
A few redundant rules have been removed as well (they were always
overridden by inline styles).
Add alert suggesting that the user switch to a connected account. This
alert is displayed when the popup is opened over an active tab that is
connected to some account, but not the current selected account. The
user can choose to switch to a connected account, or dismiss the alert.
This alert is only shown once per account switch. So if the user
repeatedly opens the popup on a dapp without switching accounts, it'll
only be shown the first time. The alert also won't be shown if the user
has just dismissed an "Unconnected account" alert on this same dapp
and account, as that would be redundant.
The alert has a "Don't show me this again" checkbox that allows the
user to disable the alert. It can be re-enabled again on the Alerts
settings page.
This component was indended to show both ETH/fiat and token balance,
but today is not used for token balance. As a result, large pieces of
this component and many props were unused in practice. The condition
about `formattedBalance` returning a falsy or `None` or `...` result
was also removed, as that doesn't seem to be possible.
The `balanceValue` passed into the `Balance` component in the asset
list has also been removed, as it isn't used.
When disabling an alert, the background `alertEnabledness` state of the
alert was being set to `undefined` instead of `false`. This didn't have
any user-facing effect, since `undefined` is falsey, but it did result
in a PropType error on the Alert settings page. This mistake was made
in #8550.
The `alertEnabledness` state is now correctly set to `false` instead of
`undefined`.
The unconnected account alert can now be disabled. A "don't show this
again" checkbox has been added to the alert, which prevents that alert
from being shown in the future.
An alert settings page has been added to the settings as well. This
page allows the user to disable or enable any alert.
The hover state background color of the "Account" in the popup home
screen menu bar has been updated to match the hover state background
color of the connected status indicator. Both hover state backgrounds
now match.
The checkbox color was sometimes incorrect after it was checked. I'm
not sure how to consistently reproduce this issue, but I was able to
make this happen most of the time if I clicked the checkbox while some
text was highlighted.
It seems that the `:checked` and `:indeterminate` pseudo-selectors were
not being applied right away for some reason. Either that or React
wasn't setting the `checked` state of the `input` element right away.
This problem has been worked around by using CSS classes instead of
pseudo-selectors. I am no longer able to reproduce the issue now.
A change made in #8284 had the unintended side-effect of making this
scrollbar appear on the home screen. Previously it was scrollable
without any scroll bar being visible.
This new dropdown component uses a native `select` element, thus
avoiding various issues encountered in attempting to reuse our existing
dropdown components for the new permission system alert modal.
The prefixed forms of `appearance` have been added temporarily so that
the component can be used in Storybook, as our Storybook config isn't
setup to do autoprefixing yet. Our real build system does handle
autoprefixing for this rule correctly already.
Resolves three different style issues due to overflow of content
and addresses an issue where UI was being squished due to available
screen real estate.
- On the choose account modal, when a user has enough accounts to need
to scroll within the account chooser, the last-connected data column
was squished. This is resolved by using a tooltip and icon for this data
rather than text printed in column.
- On the connection permission result screen where it shows the Dapp icon ->
Metamask icon, the bottom of the logos and dropshadows were being cut off
this was resolved by removing the height set on this element and allowing
it to fill the available space.
- On the confirmation screen the content appeared off center due to the scrollbar being overlayed instead of auto. This was resolved by removing some of the setting of manual overflow controls on the body element.
Tokens are now updated when the account switches after a failed account
import. The usual account switching flow (via the account menu) already
updated tokens, but this step was omitted when the account switched
after a failed import.
* Remove `estimatedGas` property from `txMeta`
The `estimatedGas` property was a cache of the gas value estimated for
a transaction when the default gas limit was set. This property wasn't
used anywhere. It may have been useful for debugging purposes, but the
same gas estimate is already stored on the `history` property so it
should be present in state logs regardless.
* Remove `gasLimitSpecified` txMeta property
The `gasLimitSpecified` property of `txMeta` wasn't used for anything.
It might have been useful for debugging purposes, but whether or not
the gas limit was specified can also be determined from looking at the
transaction history, so it's not a huge loss.
* Remove `gasPriceSpecified` txMeta property
The `gasPriceSpecified` property of `txMeta` wasn't used for anything.
It might have been useful for debugging purposes, but whether or not
the gas price was specified can also be determined from looking at the
transaction history, so it's not a huge loss.
* Remove `simpleSend` txMeta property
The `simpleSend` property of `txMeta` was used to ensure a buffer was
not added to the gas limit during gas estimation for simple send
transactions. It was made redundant by #8484, which accomplishes this
without the use of this property.
An alert is now shown when the user switches from an account that is
connected to the active tab to an account that is not connected. The
alert prompts the user to dismiss the alert or connect the account
they're switching to.
The "loading" state is handled by disabling the buttons, and the error
state is handled by displaying a generic error message and disabling
the connect button.
The new reducer for this alert has been created with `createSlice` from
the Redux Toolkit. This utility is recommended by the Redux team, and
represents a new style of writing reducers that I hope we will use more
in the future (or at least something similar). `createSlice` constructs
a reducer, actions, and action creators automatically. The reducer is
constructed using their `createReducer` helper, which uses Immer to
allow directly mutating the state in the reducer but exposing these
changes as immutable.
`removeFromAddressBook` returned a thunk that didn't return a Promise,
despite doing async work. It now returns a Promise.
The callers were updated to `await` the completion of this operation.
`addToAddressBook` returned a thunk that didn't return a Promise,
despite doing async work. It now returns a Promise.
The callers of this action creator were updated to `await` the
completion of the operation. It was called just before redirecting the
user to a different page or closing a modal, and it seemed appropriate
to wait before doing those things.
`editRpc` returned a thunk that didn't return a Promise, despite doing
async work. It now returns a Promise.
In the one place where this is used, it didn't seem important to update
the callsite to block on this finishing. Only one call followed it in
the event handler, and it didn't seem to depend on this.
`updateAndSetCustomRpc` returned a thunk that didn't return a Promise,
despite doing async work. It now returns a Promise.
In the one place where this is used, it didn't seem important to update
the callsite to block on this finishing. Only one call followed it in
the event handler, and it didn't seem to depend on this.
The `getSelectedAddress` selector has a fallback of selecting the first
MetaMask account. This is not useful. The only time the
`selectedAddress` is not set is during onboarding, before any accounts
exist, so selecting the first account wouldn't be useful anyway.

`setRpcTarget` returned a thunk that didn't return a Promise, despite
doing async work. It now returns a Promise.
The callers of this action creator didn't need to be updated, as they
were all in event handlers that didn't require knowing when the
operation had completed.
`editRpc` returned a thunk that didn't return a Promise, despite doing
async work. It now returns a Promise.
In the one place where this is used, it didn't seem important to update
the callsite to block on this finishing. Only one call followed it in
the event handler, and it didn't seem to depend on this.
Changes to the background state were being detected in the `update`
event handler in `ui/index.js` that receives state updates from the
background. However this doesn't catch every update; some state
changes are received by the UI in-between these `update` events.
The background `getState` function is callable directly from the UI,
and many action creators call it via `forceUpdateMetamaskState` to
update the `metamask` state immediately without waiting for the next
`update` event. These state updates skip this change detection in
`ui/index.js`.
For example, if a 3Box state restoration resulted in a `currentLocale`
change, and then a `forceUpdateMetamaskState` call completed before the
next `update `event was received, then `updateCurrentLocale` wouldn't
be called, and the `locale` store would not be updated correctly with
the localized messages for the new locale.
We now check for background state changes in the `updateMetamaskState`
action creator. All `metamask` state updates go through this function,
so we aren't missing any changes anymore.
`setProviderType` returned a thunk that didn't return a Promise,
despite doing async work. It now returns a Promise.
None of the callers of this action creator needed to know when it
completed, so no changes to the call sites were made.
