"error: Name is not defined" and confusing behavior on instance-level classes

Running mypy on the following example:

from typing import Type

class Foo:
    def __init__(self):
        class Bar:
            pass

        self.Bar: Type[Bar] = Bar

foo = Foo()
bar: foo.Bar = foo.Bar()

reveal_type(foo.Bar)
reveal_type(bar)

results in the following slightly confusing and seemingly contradictory output:

example.py:11: error: Name 'foo.Bar' is not defined  # on bar: foo.Bar
example.py:13: note: Revealed type is 'Type[example.Bar@5]'  # on reveal_type(foo.Bar)
example.py:14: note: Revealed type is 'Any'  # on reveal_type(bar)

Ideally, I would have expected reveal_type(bar) to reveal example.Bar@5. I'm not sure if there is a way to correctly type this code without resorting to # type: ignore right now.

Tested on mypy 0.761, Python 3.8.1.

Reproduce the example in example.py with mypy, focusing on the annotation bar: foo.Bar and the reveal_type calls. Trace how mypy handles the instance-level class reference and determine whether the reported error and Any result can be replaced with the expected example.Bar@5 type. Done means the example type-checks as intended and reveal_type(bar) reports that class type.
