[Android] Incorrect height received in endCoordinates object from 'keyboardDidShow' event

Description

I have a button component with the position:"absolute" and bottom:0. I am trying to float this component over the keyboard using Animated API. It works fine in iOS for large and small devices. It doesn't work as expected in Android. Part of the button is covered by the keyboard in some devices. Few devices show result as expected.

Steps To Reproduce

Provide a detailed list of steps that reproduce the issue.

1. Create an Animated.View in a screen (wrapped in SafeAreaView) with position:"absolute" & bottom:0
   { transform: [{translateY: keyboardMarginBottom}] } - style passed to the animated view.
2. Handle keyboardDidShow event.
   const keyboardDidShow = ({endCoordinates: {height}}) => Animated.timing(keyboardMarginBottom, { duration: 250, toValue: -height, useNativeDriver: true, }).start();

Expected Results

I expect the view to float perfectly over the native keyboard. It doesn't work as expected in Zenfone Max Pro M2 (this has notch). It works as expected in Pixel 2 emulator in Android Studio.

@Azimuthal444 is this caused by the SafeAreaView and using a phone that has a notch?
what does this change in keyboardDidShow event do? https://github.com/facebook/react-native/pull/29292/files Thanks
