super() doesn't work in @contextlib.contextmanager

[hotpxl]

The following program

import contextlib

import attrs


@attrs.define
class D1:
    @contextlib.contextmanager
    def hello(self):
        yield None


@attrs.define
class D2(D1):
    @contextlib.contextmanager
    def hello(self):
        with super().hello():
            yield None

with D2().hello():
    pass

raises TypeError: super(type, obj): obj must be an instance or subtype of type

If I use super(D2, self) it works fine.
