`overloaded function has no attribute "fset"` error when attempting to assign to base class's setter

class Foo:
    def __init__(self) -> None:
        self._value = 1

    @property
    def value(self) -> int:
        return self._value

    @value.setter
    def value(self, new_value: int) -> None:
        self._value = new_value


class Bar(Foo):
    @property
    def value(self) -> int:
        return super().value

    @value.setter
    def value(self, new_value: int) -> None:
        Foo.value.fset(self, new_value) # error: overloaded function has no attribute "fset"  [attr-defined]

playground

this is working around the fact that assigning to super().value doesn't work at runtime:

super().value = new_value  # error: Invalid assignment target [misc]

Start with the provided Foo and Bar reproduction in the linked mypy-play playground, comparing the diagnostic for Foo.value.fset with the invalid super().value assignment. Trace the checker path for overloaded attributes and property setters. Done means the valid base-class setter usage is handled without the reported attr-defined error, with appropriate coverage added for this reproduction.
