I have verified this issue and it's no longer reproducible with the latest Firefox Reality version 8-40101959 (3c2a71e). Now, the Sidebar remains displayed after resizing to a 3x size.
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).
