[Regression] RN 0.76 stretches Modal to full screen on Android API < 30 if edge-to-edge mode is enabled

[kirillzyusko]

Description

If edge-to-edge mode is enabled for the app:

WindowCompat.setDecorFitsSystemWindows(this.window, false)

And Modal is shown, then we have a different behavior (see steps for reproduction and screenshots section).

Prior to RN 0.75 we had a consistent behavior and content was always shown above the navigation bar (independently from MainActivity configuration). I hope to get this consistent behavior in RN 0.76 as well. If we want to customize navigation bar behavior (and draw a content behind them) we can take a power of this PR: #47254

So keeping all information above in the head I tend to think that this is a regression 🙂

Steps to reproduce

1. Run reproduction example on API 29
2. Click on "Show modal" button
3. Check that content goes beyond navigation bar
4. Run reproduction example on API 30
5. Click on "Show modal" button
6. Check that the content is shown above the navigation bar

I had a problem with react native modal after version 0.76.x. My modal without absolute position inside a view with flex: 1 was very displaced and even adjusting the layout the buttons inside it did not work... What solved this problem was I went to the android/gradle.properties file and disabled the new architecture (newArchEnabled=false), after that the modal behaved correctly.

Then run:

yarn start --reset-cache
yarn android
