Subject: [PATCH 1/5] Unset mouseGrabberPopup if it's removed from children
The mouseGrabberPopup is supposed to be unset in handleRelease, however
when the exit transition of the mouseGrabberPopup (that closed itself on
button press) finishes before the release event is delivered, it
unparents itself from the overlay (see
QQuickPopupPrivate::finalizeExitTransition) and the overlay sets itself
invisible if there is nothing else visible in it. Because the overlay
is not visible it handles no events anymore and the release is missed
and the grabber is never unset. When opening another non-modal popup
the overlay then will continue forwarding the events to now invisible
popup.
So when the overlay loses the currently grabbing popup as a child we need
to reset mouseGrabberPopup.
Fixes: QTBUG-95259
