deliverSinglePointEventUntilAccepted(): skip items that aren't shown
This function is called for delivering other types of pointer events
than mouse and touch: tablet, wheel and native gesture events mainly.
It calls item->window()->mapToGlobal() so a crash is theoretically
possible in rare complex cases if pointerTargets() somehow found
items that are not in the window; so we add a null pointer check to
avoid crashing.
Fixes: QTBUG-82013
