Incorrect error when argument missing from function call unpacking TypedDict

Bug Report

When supplying arguments by unpacking a TypedDict, and the TypedDict does not supply all the parameters, mypy seems to treat it as only supplying the first parameter, even if that is the one that is missing.

To Reproduce

from typing import TypedDict

def my_function(foo: int, bar: int) -> None:
    pass

class MyTypedDict(TypedDict):
    # foo: int
    bar: int

    
a: MyTypedDict = {'bar': 1}

my_function(**a) # mypy - error: Missing positional argument "bar" in call to "my_function"
my_function(bar=1) # mypy - error: Missing positional argument "foo" in call to "my_function"

https://mypy-play.net/?mypy=0.931&python=3.11&flags=strict&gist=c72be0814d2e7684453f2a8825f2e986

Expected Behavior

The line my_function(**a) should result in mypy error error: Missing positional argument "foo" in call to "my_function", as it only supplies bar.

Actual Behavior

The line my_function(**a) resulted in mypy error error: Missing positional argument "bar" in call to "my_function".

When executed, python gave this error:

TypeError: my_function() missing 1 required positional argument: 'foo'

Inizia eseguendo il riproduttore fornito di mypy-play per TypedDict e function-unpacking e confronta la diagnostica di mypy con il TypeError di Python. Traccia quindi la gestione delle chiamate **a e delle chiavi TypedDict, poi aggiungi la copertura che dimostri che l'argomento mancante è foo anziché bar.
