Not possible to exit worldReadableRoom when logged in as guest

There's no back button on the top bar.

Where would a guest user want to go? Any benefit to sending this user to the session picker because guest user doesn't even know he is a guest user. And we only register guest user when configured in a single-room mode, so perhaps this is good as is?

Even if the loading of the room fails, there is no screen for the user to go. "Login" is the only additional thing they can do, for which we have that in bottom bar. Sounds sufficient?

I think it should go to the session picker, since the user is only a guest in this session. They might want to change sessions.

I don't think the user should ever be "locked" in a screen, they should always be able to go up to the "root" screen.
