If you send a knock that is rejected, or your knock is accepted and you
are later removed from the room, do not automatically accept subsequent
invites to that room.
Note that the auto-join behaviour happened only if the page was not
refreshed after sending a knock.
Include:
- all rooms you are a member of
- knock rooms you've knocked on and are waiting for an invite to
- knock rooms you've been invited to in response to a knock
When visiting the page for a knock room you are already invited to, join
it right away instead of offering to knock (which will fail as long as
you remain invited to the room).
