Bugzilla

Bug 1688584 added the ability to exit full screen matching the behavior of Safari, but some websites seem to handle <esc> but sometimes not `preventDefault`, so this might just be a site-specific implementation issue?

For example, GitHub has a searchbox that shows a custom autocomplete. Pressing escape dismisses that UI but also causes Firefox to now exit full-screen. The same happens on Safari, so at least it's consistent.

I've also run into issues on Gmail when pressing escape to close a chat window also now exits full-screen.

Google Photos does seem to `preventDefault` if it would have done something such as exiting edit mode to view; photo view to album; single album view to albums view. But if you press escape one more time thinking it would go from albums view to the "home" view, the page doesn't actually handle that and Firefox exits full-screen. Also same issue as GitHub where pressing escape to dismiss the search autocomplete UI results in exiting full-screen.
