False positive with inline TypedDict and postponed annotations

[object-Object]

Describe the bug

When using from __future__ import annotations with the experimental inline TypedDict syntax, Pyright gives what I think is a false reportUndefinedVariable error for non-string forward references.

Code or Screenshots

Code:

from __future__ import annotations
from typing import TypedDict

string: dict[{"forward_ref": "ForwardRefType"}]

# note: `value = dict[{"forward_ref": ForwardRefType}]` *does* raise NameError
non_string: dict[{"forward_ref": ForwardRefType}]  # Pyright error occurs here

class TypedDictType(TypedDict):
    forward_ref: ForwardRefType

ForwardRefType = str

Error:

(venv) PS D:\Users\redacted> python test.py
(venv) PS D:\Users\redacted> pyright test.py
D:\Users\redacted\test.py
  D:\Users\redacted\test.py:7:34 - error: "ForwardRefType" is not defined (reportUndefinedVariable)
1 error, 0 warnings, 0 informations

VS Code extension or command-line

Tested using the command line tool.
Pyright: 1.1.326
Python: 3.11.3

Inlined TypedDict is an experimental feature intended to gather feedback about a potential future extension to the type system. It's likely to change or be removed, so please don't make use of it in any production code.

Given the status of this feature, I don't generally entertain bug fixes (especially edge cases), but this one happens to be trivial to fix, so I'll do so.

This is addressed in pyright 1.1.327, which I just published. It will also be included in an upcoming release of pylance.
