[issue36178] type.__init__ called instead of cls.__init__ when inheriting from type.

[Hameer Abbasi]

New submission from Hameer Abbasi <einstein.edi...@gmail.com>:

I may be completely misunderstanding here, but: here's a reproducible example:

class MyMeta(type):
    def __new__(cls, *args, **kwargs):
        print('__new__', *args, **kwargs)
        super().__new__(cls, *args, **kwargs)
    
    def __init__(self, a):
        print('__init__', *args, **kwargs)
        super().__init__(*args, **kwargs)

class A(metaclass=MyMeta):
    pass

MyMeta('A', (), {'__module__': '__main__', '__qualname__': 'A'})


Output:

__new__ A () {'__module__': '__main__', '__qualname__': 'A'}
__new__ A () {'__module__': '__main__', '__qualname__': 'A'}

Is this by design?
