When overriding APIView.get_permissions, mypy complains about return type incompatebility

[guldfisk]

In this example:

from rest_framework.viewsets import GenericViewSet
from rest_framework.permissions import BasePermission


class MyView(GenericViewSet):
    def get_permissions(self) -> list[BasePermission]:
        ...

Mypy generates the following error:

example.py:6: error: Return type "List[BasePermission]" of "get_permissions" incompatible with return type "List[_SupportsHasPermission]" in supertype "APIView"  [override]

Even though BasePermission implements _SupportsHasPermission
