ESLint rules have been added to enforce our JSDoc conventions. These
rules were introduced by updating `@metamask/eslint-config` to v9.
Some of the rules have been disabled because the effort to fix all lint
errors was too high. It might be easiest to enable these rules one
directory at a time, or one rule at a time.
Most of the changes in this PR were a result of running
`yarn lint:fix`. There were a handful of manual changes that seemed
obvious and simple to make. Anything beyond that and the rule was left
disabled.
* Prevent automatic rejection of confirmations
Confirmations are now only automatically rejected if a user explicitly
closes the notification window. If we close the window programmatically
because there are no notifications left to show, nothing gets rejected.
This partially avoids a race condition where a confirmation gets
rejected automatically without the user having seen the confirmation
first. This could happen if the confirmation was processed just as the
notification window was being closed.
It's still possible for a confirmation that the user has never seen to
get rejected as a result of the user closing the window. But at least
now it's no longer possible for a confirmation to get rejected in this
manner after the user resolves the last confirmation in the queue.
* Fix bug that prevented automatic closure detection
All windows were being detected as explicit window closures,
essentially just as they were previously, because this variable was
cleared too soon.
* Re-open popup when necessary
After the window is automatically closed, a confirmation may have been
queued up while the window was closing. If so, the popup is now re-
opened.
