I have verified that this issue is no longer reproducible with the latest Firefox Reality version 9-40240151 (7e03c94) build. The media controls are at eye level. Also, the widget seems to be slightly bigger now.
Tested on Oculus Go (Android 7.1.2), Oculus Quest (Android 7.1.1), HTC Vive Focus Plus (Android 7.1.2) and HTC Vive Focus (Android 7.1.2).
