WhiteBoard tab needed to broadcast cam/audio

If you enter a room that does not have a WB "tab" open, then you can not enable audio or video.  You can click on the icons and it says they are enabled but you will not get the "pop up" box previously talked about (see 1st image).

If the room already has a WB tab open then all works as expected, it is just if you are in a room when no WB tab open, then it doesn't work. 

Looks like this is only the case if you have not "hidden" the WB element in the room settings.  If you hide that element, then it works as expected.  With WB element not hidden then you must have a WB tab open prior to clicking on the mic/cam functions to have the ability to broadcast audio/video.
