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"

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'

Beginne damit, den bereitgestellten mypy-play TypedDict- und function-unpacking-Reproduzierer auszuführen und mypys Diagnose mit Pythons TypeError zu vergleichen. Verfolge dann die Behandlung von **a-Aufrufen und TypedDict-Schlüsseln und füge anschließend Abdeckung hinzu, die zeigt, dass das fehlende Argument foo und nicht bar ist.
