I have verified this issue and it's no longer reproducible with the latest Firefox Reality version 10-141111916 (d9a7eec). I was not able to reproduce this issue in 10 attempts an I think it's safe to close it as verified fixed an open a new one if encountered in the future since is intermittent.

Tested on HTC Vive Focus (Android 7.1.2), Oculus Quest (Android 7.1.1) and Pico Neo 2 (Android - 8.1.0) devices.
