Failed metric events on the opt-in page no longer leave the user stuck
on that page. If the metric events fail, they still bubble up as errors
to be caught by Sentry and logged to the console, but the user is still
brought to the next page.
Fixes#9800
We were unable to deliver this public dashboard as we had originally
anticipated, and this is no longer a priority for the team. We may
revisit this idea in the future, but for now it has been removed from
our list of commitments.
* Update i18n-helper to allow substitutions of react components and wrapping of translation substrings
* Simplify code in i18n-helper.js related to substitutions, including react substitutions.
* Remove wrapper support from i18n in favour of using translations in substitutions.
* Fix i18n-helper substitution logic: ensure correct index of substitution is applied
* Throw error if there are not enough substitutions for a translation phrase
* Adds unit tests for now i18n-helper substitution functionality
* Fix grammar, react element line spacing and test layout+readability in i18n-helper.test.js
* eslint: Check for unused function arguments
* eslint: Ignore unused '_' in argument list
Also allow any number of '_' e.g., '__' or '___' which is to be used sparingly
* Remove and rename unused arguments
