Regression
Yes
IPointerExitHandler.OnPointerExit is called incorrectly when running via Script
How to reproduce:
1. Open the attached "1419953.zip" project
2. Open the "Scene" Scene
3. Enter Play Mode
4. Move the mouse pointer onto the colored Canvas GameObjects
5. Open the Console Window
Expected result: "Exit Parent" is only printed when you leave the whole canvas
Actual result: Once you enter the "Child" Canvas GameObject, "Exit Parent" is printed
Reproducible with: 2021.2.0a21, 2021.3.1f1, 2022.1.0f1, 2022.2.0a11
Not reproducible with: 2019.4.38f1, 2020.3.34f1, 2021.2.0a20

Absolutely maddening change. Poor decision.

It took a little detective work but in case it helps anyone else, here is basically what the "resolution note" means. PointerEventData has been updated to contain a new boolean property called "fullyExited", which you can use like this:
public void OnPointerExit (PointerEventData eventData)
{
if (eventData.fullyExited)
; // execute previous behavior here
} -

Could you explain that in more detail? What flags are you referring to? PointerEventData does not seem to have any flags.
I am not familiar with "ono" nor can I access the link you posted.

Resolution Note:
We use "fully exited" flag to indicate pointer position. when "fully exited" =false, it indicates enter child elements even though it's still in the parent. when pointer is completely out, "fully exited" flag will be true. and therefore the additional call. We are planning to make a doc update though, for this change.
