With this more of the
controls that look like buttons can be operated via the keyboard and
navigated to by screen reader users. This includes editor buttons such
as File upload, Audio / Video call, Right pannel hide button, Jump to
the bottom timeline button, and some more buttons found in the user
settings.
Also I have added alt texts to some images that in turn label buttons
which these happen to be packed in and removed some untranslated alt
texts from decorative non-actionable images that might add more
verbosity when talking about screen reader user experience.

Because the onClick was on a fullpage div, the browser was firing it regardless of how far the mouse moved. The onClick event itself doesn't give us any sort of travel distance, or a start point we can use to determine if they clicked a scrollbar or something. This means we have to rely on good ol' fashioned mouse down and up events to see if the user moved their mouse during their click.
If the user's click starts in a valid container, we record the coordinates. This is so we can easily identify when the user clicks inside something like the settings container itself. When the user releases their mouse, we determine how far they moved their mouse - if the distance is within some threshold (~5 pixels in this case) then we can count it as a click. Because we've already filtered on the component they started their click in, we can safely rely on the presence of coordinates as a flag that they are in the right container, combined with the fact that they can't stray too far before their click not counting anyways.
_loadMembersIfJoined is called from
_onRoomLoaded < _onRoomViewStoreUpdate, before incoming state
from the store is applied to this.state, so looking up the room
with this.state.roomId doesn't always work, which would cause
the members not to be loaded. Pass in the room instead.
I haven't found anyone who can justify to me why we need
more complicated plurals for i18n (even in Polish) for
%(senderName)s added %(addedAddresses)s and removed %(removedAddresses)s as addresses for this room.
This is more reliable with LL enabled as the syncing user is
only known when it was active in the current timeline
or when the members have been loaded
when peeking, the members weren't being loaded at all because
the room wasn't available yet,
and the need for loading the members was never re-evaluated after that.
This only loads the members once the user has joined the room,
which also helps to avoid load all the members before an invite
is accepted.
This was causing annoying exceptions on latest Chrome. Use
document.fullScreenElement to detect if we're fullscreen and don't
try to exit if we aren't.
