Description

To make a separate issue of:
https://github.com/facebook/react-native/issues/36710#issuecomment-3204826621

It's been like 1 year there is many issues reported on Android about onPress not fired (in issues of this repo and by a lot of end-user).
Since I cannot reproduce because a lot of this issue are "random", I was looking for an alternative with an onPressOut workaround.
Was able to implement a full working workaround on iOS (scroll management, hitslop, ...) but when switching to Android everything was broke. My solution was based on locationY and locationX but after investigation, I noticed that the value of locationY and locationX on Android is not correct.

For exemple, when the onPressOut is triggered because the touch goes out of the screen, the locationY is equal to pageY.
When the onPressOut is trigger after the touch leave the Pressable, but still on another Pressable (stacked Button for exemple). The locationY looks like it's the value inside the second Pressable (expected 80, but received 15 for exemple).

Impact Touchables (WithoutFeedBack, Opacity, ...).

I don't know if it's the root-cause of all onPress issue, but might not help to handle it correctly.

In the code, found out that there is a "Legacy" / "non-legacy" logic that might explain why it's only on new-arch.

Steps to reproduce
  1. Create two Pressable with onPressOut, log the locationX and locationY
  2. Start pressing the first Pressable the slide quickly to the second one.
  3. The onPressOut of the first one is triggered but display invalid value locationX/Y (supposed to be the calculated values of the second Pressable).

Research direction

Start with ReactAndroid/src/main/java/com/facebook/react/uimanager/events/TouchesHelper.kt around the referenced line and run the mandatory rn-pressabe-issue-location reproducer on Android with the new architecture enabled. Compare locationX and locationY from the first Pressable's onPressOut while moving into the second or off-screen; done means the reported coordinates match the affected Pressable's expected values.
