    Description

      Hello PySide devs,

      With PySide6 6.5.3, there is an issue when disconnecting signals.

      from PySide6 import QtCore

class Parent(QtCore.QObject):
    sig = QtCore.Signal()

    def pslot(self):
        pass

class Child(Parent):
    pass

x = Child()
# disconnecting slot defined in parent fails since PySide >= 6.5.3
x.sig.connect(x.pslot)
x.sig.disconnect(x.pslot)

      The key for triggering the failure is that the signal must come from an inherited class member.
