This adds a support a notification at the top of the screen that
alerts a user they’ve muted a stream and gives them the option to
unmute if it was an accident.
The notification disappears automatically after 4s, but if a user
moves their mouse over the notification, the timer resets to 2s after
the user moves their mouse off the notification, to make it easy for
users to read the full message and decide what to do.
