Infinite loop of view_room dispatches when viewing a room you're not in

Might be related: #8075

1. Receive a message/permalink for a room you're not in
2. Click the permalink
3. Observe infinite spam in the console

This appears to be because the OpenRoomsStore has an outdated RoomViewStore for the active room, as it should be showing the target room, not the old room. This leads to it dispatching updates in a loop because none of the stores match the room ID attempting to be seen.

Looks like it somehow causes a storm of focus_composer dispatches too?

#8130 is likely related and even the same issue.

For documentation purposes, the easiest way people have run into this is:

1. Upgrade a room
2. Click "The conversation continues here" without accepting the invite to the new room
3. Bad things happen

This appears to have been fixed by backing out tiled view - closing.
