Video chat controls are hidden by the picture-in-picture of my camera

### Steps to reproduce

1. Start video chat
2. Right click on it and select Show Controls
3. Can't access controls


This is screenshot of the bottom-right of the video window in Firefox. The hidden controls are for fullscreen, maybe volume and something else like HD or not but I have no idea since can't see them.

### Outcome

Ideally, it would be great if the picture-in-picture of my own camera could either be

1. closed (by option in right click menu), or
2. moved around (by mouse drag and drop), or
3. positioned at the top-right or top-left of the window where it would not interfere with browser controls for the video stream
