[Regression] Parent Button is not hovered if a child button is hovered

Expected behavior: When a child button of a button is hovered, the parent remains hovered. (see attached image correct.png)

Actual behavior: When the child is hovered, the parent is no longer hovered. (see attached image incorrect.png)

The behavior can be reproduced with the attached main.qml.

Regression: Worked until Qt 5.15.2
