Combing two special mapping functions confuses Mypy

Bug Report

Combing two special mapping functions confuses Mypy (and Pylance) and I can't fix the error using type annotations.

To Reproduce

code

Actual Behavior

main.py:70: error: Cannot infer type argument 1 of <dict>  [misc]
main.py:70: note: Try assigning the literal to a variable annotated as dict[<key>, <val>]
main.py:79: note: Revealed type is "builtins.dict[Any, Any]"
main.py:84: error: Unpacked dict entry 0 has incompatible type "dict[Info[str], Info[str]]"; expected "SupportsKeysAndGetItem[Unique[str] | str, Unique[str] | str]"  [dict-item]
main.py:88: error: Unpacked dict entry 1 has incompatible type "dict[Unique[str], Unique[str]]"; expected "SupportsKeysAndGetItem[Unique[str] | str, Unique[str] | str]"  [dict-item]
main.py:92: error: Unpacked dict entry 2 has incompatible type "dict[Info[str], Info[str]]"; expected "SupportsKeysAndGetItem[Unique[str] | str, Unique[str] | str]"  [dict-item]
Found 4 errors in 1 file (checked 1 source file)

Your Environment

• Mypy version used: 1.4.1
• Mypy command-line flags: /
• Mypy configuration options from mypy.ini (and other config files): /
• Python version used: 3.11

Start with the linked reproduction and its main.py using mypy 1.4.1, then inspect the type inference and dictionary-unpacking paths involved in the reported errors. Done means the reproduction no longer reports the four errors while preserving the expected inferred types.
