    Description

      Hi,

      We have noticed a bug on our project with new changes we did while testing PySide2 (instead of PyQt5).

      It appears that self.sender() is None in some circonstancies.

      I join a small test file (test.py) to reproduce the problem.

      Here is the output on my machine:

       

      == Base ==
__callback OK
callback OK
== Inherited ==
__callback ERROR: None
callback OK
== End ==

      As you can see, if we execute the base class directly or the inherited class (which only inherit the base class), the result is not the same.
