    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.
