Steps to reproduce:
1. Open attached project
2. Open "CheckAreasVisually" scene
3. Build and run on a device with some cutout (Like a notch or camera cutout)
4. Orient the device to Portrait mode
5. Click the button till the status indicates "Windowed" mode and the Navigation bar appears at the bottom
6. Observe the Red area (that indicates the cutout) disappear

Expected: Cutout Rect coordinates should be adjusted to match actual cutout on device once the Navigation bar appears
Actual: Cutout Rect coordinates are not adjusted and since the Navigation bar takes up some extra space, the Rect coordinates end up pointing to just outside the screen space
