The bug occurs if Optional is imported from typing_extensions instead of typing.

from typing_extensions import Optional

def foo(x: Optional[int] = None):
     pass

Treat all typing_extensions members as typing aliases (#9335)
195f7c0 
## Summary

Historically, we encoded this list by extracting the `__all__`. I went
to update it, but... is there really any value in it? Seems easier to
just treat `typing_extensions` as an alias for `typing`.

Closes #9334.
