Describe the bug
I created a generic TypedDict which should have extra_items=T of the same type, however the sub scripted type is not resolved and is rather T@TD.

Code or Screenshots
Code sample in pyright playground

from typing_extensions import TypedDict

class TD[T](TypedDict, extra_items=T):
    a: T

d1: TD = {"a":1}
d2: TD[int] = {"a":1}

reveal_type(d1["other"])  # T@TD  # expected Unknown
reveal_type(d2["other"])  # T@TD  # expected int
