* Update our cancel icon
The cancel icon we're using in the app has drifted out of sync with the ones used in our designs. We also had two identical-looking icons, so this consolidates them into one.
I've simultaneously updated our chevron icons, since in the case of the 'jump to unread' timeline button, it became clear that the weight of the new close icon did not match the thinner chevron.
* Don't squish bottom/top-aligned tooltips near the edge of the screen
* Close the timeline panel when returning to the fullscreen timeline view
* Add layout switching capabilities to ElementCall
* Bring the room header in line with the group call designs
* Bring the PiP header in line with the group call designs
* Fix lints
* Clarify tooltip CSS calculations
* Test PipView
* Expand RoomHeader test coverage
* Test PipView more
* Improve accessibility and testability of Tooltip
Adding a role to Tooltip was motivated by React Testing Library's
reliance on accessibility-related attributes to locate elements.
* Make the ReadyWatchingStore constructor safer
The ReadyWatchingStore constructor previously had a chance to
immediately call onReady, which was dangerous because it was potentially
calling the derived class's onReady at a point when the derived class
hadn't even finished construction yet. In normal usage, I guess this
never was a problem, but it was causing some of the tests I was writing
to crash. This is solved by separating out the onReady call into a start
method.
* Rename 1:1 call components to 'LegacyCall'
to reflect the fact that they're slated for removal, and to not clash
with the new Call code.
* Refactor VideoChannelStore into Call and CallStore
Call is an abstract class that currently only has a Jitsi
implementation, but this will make it easy to later add an Element Call
implementation.
* Remove WidgetReady, ClientReady, and ForceHangupCall hacks
These are no longer used by the new Jitsi call implementation, and can
be removed.
* yarn i18n
* Delete call map entries instead of inserting nulls
* Allow multiple active calls and consolidate call listeners
* Fix a race condition when creating a video room
* Un-hardcode the media device fallback labels
* Apply misc code review fixes
* yarn i18n
* Disconnect from calls more politely on logout
* Fix some strict mode errors
* Fix another updateRoom race condition
