Pyright fails to find cookies member of Django's HttpResponse

[apollo13]

Describe the bug
Pyright fails to discover members on HttResponse but only in strict mode, the following code works fine on mypy (no matter the mode).

Code or Screenshots

from typing import reveal_type

from django.http import HttpResponse

response = HttpResponse()
reveal_type(response)
print(response.cookies["_up_method"].value)

django and django-stubs are installed. The relevant type in the stubs file is defined here: https://github.com/typeddjango/django-stubs/blob/87f48b3ae62cd983c72f2e9639e80a9a7c6e487f/django-stubs/http/response.pyi#L26 -- are the stubs somehow not used or am I doing something wrong?

The output:

/home/florian/sources/unpoly/python-unpoly/test.py
  /home/florian/sources/unpoly/python-unpoly/test.py:6:13 - information: Type of "response" is "HttpResponse"

Pyright isn't "failing to discover members" in this case. It's simply telling you that the evaluated type of the member is Unknown. In strict mode, the reportUnknownMember diagnostic check is enabled.

This appears to be a bug in the type stubs. The response.pyi type stub declares the type of cookies as SimpleCookie. This symbol comes from cookie.pyi and is defined as a variable SimpleCookie: Any. Variables are not allowed to appear within type annotations, so pyright treats it as an Unknown type. I suspect that the intent of the stub authors was to create a type alias (SimpleCookie = Any) or a class that derives from Any (class SimpleCookie(Any): ...).

I see, sorry for the noise. Will see about getting this fixed upstream.
