Reproduce the issue on Android 10 with SDK v3.11.1 by opening full-screen preview, hiding the title menus by tapping the image, and pressing the system Back button. Inspect the full-screen preview and navigation-bar handling around that sequence. Done means the navigation bar and UI no longer overlap after returning.
