fix: overlapping buttons cause buttons to stop being responsive (#3371)

## Description

Partially resolves problem in #3370

This PR fixes an issue where a behind button could stay stuck in the
"pressed" state if another overlapping button took the responder. By
adding a check in onTouchEvent, we ensure that only one button can stay
pressed at a time. If another button is already the responder, the
behind button cancels itself and won't remain highlighted.

It will not solve the issue if both button are not exclusive. For this
edge case better solution is needed.
