Bug description

I get an issue similar to #8522, but it seems to have a different cause. Supposedly this issue was fixed in pylint 3.0.0, but I still see it.

Code:

class A:
    def __init__(self) -> None:
        self.var = 2

class B:
    def __init__(self) -> None:
        self.a_obj = A()

    def func(self):
        self.a_obj = A()
        self.a_obj = A()

Result:
