Show the breakout room number while in the breakout room

[vzanini]

When you go in a breakout room, it's hard to see what room you belong to. A message is only briefly shown, if you miss it, you miss it. People may not be friendly enough with the tool to go and figure out what room they belong to.

When in a breakout room, there could be people sharing a screen, or a Zoom app running. All of these take real estate in the top bar, and the breakout room number disappears.

I would prefer for the breakout room to always be shown. This is useful for context, and simplifies the user experience.

For example, it could be important to know the room number when the host has assigned exercises to individual rooms, and sends people randomly there. People right now get confused because they can't see their room's number.
