Return value annotation with pass statement

[zkksch]

mypy==0.750

class Foo:
    def bar(self) -> int:
        pass


x: int = Foo().bar()
y = x + 2

I expected "Incompatible return value type", but mypy says that there are no issues. Is it bug or I can configure mypy in some way to disallow this kind of cases?
