Reg->5:15.2: Segfault calling contextMenuEvent for QGraphicsTextItem with TextEditorInteraction

Python crashes with a segmentation fault when contextMenuEvent for a QGraphicsTextItem with setTextInteractionFlags(QtCore.Qt.TextEditorInteraction) is called.

Repro:

Run attached script.py and right click in the canvas.

On PySide2 5.14.2.3 and 5.15.0 this opens a context menu showing Undo, Cut, Copy, Paste etc.

On PySide2 5.151 and 5.15.2 this casues a segmentation fault.

Steps to reproduce in Qt:

• run qtbug89563.zip
• right click text item

or

• Patch the subattac example qtbug89563_subattac_repro.diff
• Launch, start new game. right click on top right progress text item
• Observer crash qtbug89563_subattac_stack.txt

This was reported against Qt for Python 5.15, but it does not happen in Qt for Python 6. Maybe it was fixed in Qt 6?
