When allowed orientation or forced orientation is set to Portrait and set to fullscreen, app opens in a phone-sized screen on Android 9 Chrome Os devices

How to reproduce:

1. Open orientations project, which link is in the comments
2. When selected platform is Android, go to Player Settings -> Resolution and Presentation
3. Make sure that Fullscreen Mode is set to Fullscreen Window, resizable Window is enabled
4. Change Orientation to Autorotation and allow only Portrait. 
5. In Orientations.cs script comment this line Screen.orientation = ScreenOrientation.Portrait; which is called from Start()
6. Build and run on Chrome OS device, which is in Laptop mode

Actual result: App starts in phone sized window

Expected result: App Starts in LandscapeLeft fullscreen (because we allow autorotation to Portrait, but laptop mode needs to force to LansdcapeLeft.)

Note: Same result is when user has all orientations enabled in Autorotation, but then changes it to default orientation Portrait. In the script Orientations.cs on Start() one needs to add Screen.orientation = ScreenOrientation.AutoRotation;

 

Tested and reproduced:

HP Chromebook 14a G5, ChromeOS version: 102.0.5005.75 (64 bit), Android version 9 Build number: R102-14695.85.0
Lenovo Chromebook Duet 2 in 1, ChromeOS version: 103.0.5060.64 (32 bit), Android version 9 Build number: R103-14816.82.0

Tested and didn't reproduce:

Google Pixelbook, ChromeOS version: 102.0.5005.75, Android version 11 Build number: R102-14695.85.0 <- On this device on the most marked versions app opens Fullscreen as a Portrait, but reports Landscape. On Unity 2022.2.0b4 and 2023.1.0a6 when app is set to autorotate it always opens also as phone-sized window. Bug doesn't reproduce only after latest Chrome OS orientation bugfix PR and app opens as Landscape and reports Landscape Left.
