false-positive `name-defined` regression with dataclasses and shadowing

Bug Report

This file:

from dataclasses import dataclass
import collections


@dataclass
class Shadow:

    collections: collections.deque
    other: collections.defaultdict


print(Shadow(collections.deque(), collections.defaultdict()))

is perhaps a bit unorthodox, but runs fine, because the collections: ... doesn't actually shadow the module when defining other.

Actual Behavior

mypy v0.950 was happy with it, but mypy v0.960 claims that:

test.py:9: error: Name "collections.defaultdict" is not defined

Introducing commit

Bisected to 03901ef657daf6f477e6fe933c42ac270cf5034b ("Running dataclass transform in a later pass to fix crashes (#12762)", @JukkaL)

Your Environment

• Mypy version used: v0.960
• Mypy command-line flags: none
• Mypy configuration options from mypy.ini (and other config files): none
• Python version used: 3.10.4
• Operating system and version: Archlinux

Tái hiện báo cáo bằng ví dụ test.py được cung cấp, sau đó kiểm tra commit 03901ef657daf6f477e6fe933c42ac270cf5034b và các thay đổi dataclass-transform mà commit này đã đưa vào. Truy vết lý do annotation trên collections ảnh hưởng đến annotation tiếp theo và xác minh rằng ví dụ không còn tạo ra lỗi false-positive name-defined.
