ListView.get_queryset() cannot be treated as a queryset

Bug report

What's wrong

The return type of get_queryset on a ListView seems to be _SupportsPagination[Any], which is throwing an error when I try and add a select_related to the queryset.

Apologies if I'm missing something here (entirely possible!), but I've been going back and forth. I can see it's coming from the MultipleObjectMixin.

django-stubs/django-stubs/views/generic/list.pyi

Line 21 in d283970

def get_queryset(self) -> _SupportsPagination[_M]: ...

class MyModelList(ListView): 
    ...
    
    def get_queryset(self): -> QuerySet[Any]:
        qs = super().get_queryset().select_related("city")

There's nothing overly complicated about the model setup here, I just want to add the select related to the base queryset.

How is that should be

super().get_queryset() should (probably?) not throw a type error when I treat it as a queryset in a ListView
