Android: navigation bar no longer auto-hides

Is there an existing issue for this?

• This is a bug in RetroArch frontend
• I have searched the existing issues

Description

Since version 1.18.0, the navigation bar no longer auto-hides after being accidentally shown. The only way to hide it is by going to home screen then return back to the application. Here is a screencast demonstrating this issue:

Expected behavior

The expected behavior is like the one in version 1.17.0 where navigation bar will auto-hide itself.

Steps to reproduce the bug

1. Use Retroarch version >=1.18
2. Swipe your bottom screen to show the navigation bar
3. The navigation bar will keep staying on screen.

Reproduce the navigation-bar behavior on Android 10 using RetroArch 1.18 or newer, then compare it with the expected behavior shown for version 1.17.0. Review commit 5452999 as the reported bisect point; the fix is complete when swiping up to show the navigation bar no longer leaves it permanently visible.
