Fast flicking during x/yanimator animations caused crash.
This bug was found during the debugging of
QTBUG-44308, the cause is that fast flicking kicks items out of viewport, if they were in transition would abruptly having the problems of QTBUG-44308, and also some tracking data structure ( here releasePendingTransition of QQuickItemViewPrivate got corrupted during handle invisible items animation).
