Black screen on some Android devices when "Show Splash Screen" is disabled in the Project Settings

How to reproduce:
1. Create a new 3D URP project
2. In the Player Settings make sure “Show Splash Screen” is disabled
3. In the Build Settings make sure WebGL is selected as the Target Platform
4. Press Build
5. Host build locally (I used XAMPP changing Config → httpd.conf → DocumentRoot and Directory paths to the build path)
6. Open build on the Android device (syntax example for accessing hosted build on a browser “ip:port”)

Expected result: Visible empty scene
Actual result: Scene is dark

Notes:

• Not reproducible on the Windows Standalone player and in the Game View
• Not reproducible on Windows PC (Tested with Chrome browser)
• Not reproducible if the Splash Screen is enabled
• Issue might be inconsistent so for example instead of entering the URL to the device browser you can create and scan the QR code to open the WebGL Player
• Didn’t search for a regressed version since this issue is not consistent there is a very high chance the regressed version I will find will be incorrect
• Couldn’t test on iOS due to the errors in the browser, but from the description and provided devices this issue only seems to be reproducible on lower-end and older Android devices
