I have verified this issue is no longer reproducible with the Firefox Reality version 8-33472001 (6ba3881) build. Exiting immersive mode using the controller now repositions the window(s) in front of the user.
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).
