Description
A working FreeCAD+Plugin combo is migrated from QT5 to QT6.
The component of interest is a PySide QTableView, no C++ code is involved.
This QTableView is used both as child of QMainWindow as well as of QDockWidget.
In QT5: this QTableView works fine both in QMainWindow and QDockWidget
In QT6: this QTableView works fine in QMainWindow but crashes when in QDockWidget
