request.FILES items are resolved as UploadedFile | list[object] instead of UploadedFile

Bug report

It seems that multidict items are not resolved correctly.

if request.FILES:
    for key, uploaded in request.FILES.items():
        reveal_type(uploaded)

What's wrong

Type is resolved as:

UploadedFile | list[object]

instead of just UploadedFile.

    def items(self):
        """
        Yield (key, value) pairs, where value is the last item in the list
        associated with the key.
        """
        for key in self:
            yield key, self[key]

So if there are multi values under one key ... only last item in the list is returned.

How is that should be

Type should be just UploadedFile.
