Reparenting items with animation to null causes crash in QSGNode::setMatrix

Reproduction:

Run the attached QML file and just click on the window. It crashes immediately. Reproducible %100.

What happens:

Setting the parent of a quick item invalidates its scene graph nodes :

https://code.woboq.org/qt6/qtdeclarative/src/quick/items/qquickwindow.cpp.html#1704

But those items are cached in QQuickAnimatorJob:

https://code.woboq.org/qt5/qtdeclarative/src/quick/util/qquickanimatorjob_p.h.html#QQuickTransformAnimatorJob::Helper::node

And the cache is not updated after the deletion hence QQuickAnimatorJob accesses a dangling pointer :

https://code.woboq.org/qt5/qtdeclarative/src/quick/util/qquickanimatorjob.cpp.html#415

The stack trace is almost same as the one mentioned in this issue : QTBUG-43294

However I don't see the markDirty() call at the end. I've attached the traces.

Fix:
The issue is fixed if we update the QQuickAnimatorJob cache.  The proposed patch in QTBUG-43294 ( https://codereview.qt-project.org/c/qt/qtdeclarative/+/101974 ) properly fixes the issue. I guess the author was bitten by something else and thought that that's not a correct fix and abandoned his diff. 

Can we just resurrect that patch ? If not, I can send a new one.
