Navigation gestures / bar ignore `requestedOrientation`

[sebastinto]

Describe the bug

When using Activity.setRequestedOrientation() in a third-party app to lock orientation in portrait or landscape orientation, the navigation gesture bar will ignore orientation changes when Niagara Launcher is the default launcher.

In other words, when the app UI is in landscape mode but the navigation bar being positioned at the short right edge of the screen while it should be at the long bottom edge of the screen. This also breaks navigation gestures.

Switching back to the Pixel Launcher fixes the issue.

Steps to reproduce

1. Activity.requestedOrientation = ActivityInfo.SCREEN_ORIENTATION_USER or Activity.requestedOrientation = ActivityInfo.SCREEN_ORIENTATION_PORTRAIT
2. Activity.requestedOrientation = ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE
3. nav bar does not reflect new orientation

Does the issue also occur with other 3rd-party launchers?

Problem doesn't occur with other launchers

Further observations:

• setting Allow home screen rotation to ON fixes the issue
• I could not replicate the issue with a couple of other 3rd-party launchers I tried to set as default launchers (Smart launcher 6 and Microsoft Launcher)

This definitely strongly suggests Niagara as being the source of the issue.

Kind of weird that it's only affecting the navigation bar and not the entire UI too. The issue does not occur when using the 3-button navigation mode.
