Strange typing issue with JsonObject

[camertron]

We encountered a bug today that I would have expected mypy to catch. Our code looks something like this:

from aiocometd.typing import JsonObject

def some_func(response_message: JsonObject) -> None:
    reveal_type(response_message)

Mypy output:

file.py: note: In member "some_func":
file.py:203:25: note: Revealed type is 'Any'

I can see that aiocometd defines JsonObjectto be a Dict[str, Any], so why does mypy think the response_message is of type Any?

This might be a mypy bug, but I thought I'd ask here first.

Ah ok I didn't realize we had explicitly added an ignore for aiocometd to our mypy.ini, apologies! Removing the ignores however results in a bunch of warnings of the form "Cannot find implementation or library stub for module named 'aiocometd.typing'" Any ideas? If not feel free to close this issue.
