- added `toggleParentReplyMode()` to comment component's props so clicking Reply on a reply opens the reply form on the top-level parent to emphasise we only support 1-level deep replies and avoid unexpected nesting
- adjusted conditional so "Reply" button is shown in `<CommentMenu>` when a parent is present (behind labs flag)
- updated `useLabs()` to always return an object so we don't need to add nullish checks everywhere
# Conflicts:
# apps/comments-ui/test/e2e/actions.test.ts
no issue
- a change in browser version/dependency versions/playwright/something else has made this test flaky because the reply editor form loses focus when the expertise field gains focus (this doesn't happen in the browser) meaning when we get to our assertions the elements we care about are missing
- forcing focus back puts us into a known state for our assertions

- `props.innerRef` in `<IFrame>` was inadvertently assumed to always exist, sometimes throwing an error on render when certain popups like the profile settings modal were opened resulting in the app crashing and the whole comments block disappearing
- added a guard to ensure the ref exists before trying to set it
- updated tests so the profile modal route is tested

- App component now uses React hooks intead of React class component
- App is now written in TypeScript
- All JavaScript is now removed from the Comments-UI project
- Removed `PopupNotification` because these were never displayed
- Removed `action` from AppContext (never used)
- Moved options parsing out of `index.ts` into a separate utility file,
similar to the signup-form
- Improved reliability of some editor tests by always waiting for the
editor to be focused (was not always the case) + added an utility method
for this
