Not a solution but this was introduced in python/typing_extensions#165, i.e. a recent version of typing_extensions

[charliermarsh]

Ah, ok, this was fixed in python/typing_extensions#162.

[charliermarsh]

This should be fixed in 2023.18.0 and later, we updated typing_extensions past that version. Let me know if not!
