Pop-up camera list doesn't scroll

Hi all, I just installed 2.0.6173 on Ubuntu 18.04 and I can only see the first three of my video sources in the pop-up list (either in the lobby, or once I have entered the room). It looks like the list disappears off the bottom of the page, but I can’t scroll down.

I get the same results on meet.jit.si.

If I change the video source from the Settings menu though, all the cameras are visible and usable.

The older Jitsi install I have (2.0.5390-1) can scroll thru the camera list no problem.

I’m using the latest Chrome and Brave on Mac 10.14. Unfortunately I don’t have much else to test it with right now.
