I have verified this issue and it's no longer reproducible with the Firefox Reality version 10 RC5 (e84d3c9). The buttons are now displayed when dismissing the libraries after resuming the app.

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