Thanks for the report!

Slimmer reproducer without multiple bases:

class Window:
    ...

class Win(Window):
    def __init__(self, txt):
        super().__init__(txt)

Win('hello')

I'm assuming that this case is missed in this block of code:

I am looking to solve this one but I am not able to get how to add this condition to the above mentioned code block?
