Unpacking unions of tuples skips type checking

Bug Report

mypy applies type checks when passing an unpacked tuple to a function, but it seems to skip the checks when passing a variable that is a union of tuple types.

To Reproduce

def inner(_name: str, _num: int) -> None:
    ...

# mypy passes as expected
def fun1(name_and_num: tuple[str, int]) -> None:
    inner(*name_and_num)

# mypy errors as expected
def fun2(name_and_num: tuple[str, float]) -> None:
    inner(*name_and_num)

# mypy passes *but should error*
def fun3(name_and_num: tuple[str, int] | tuple[str, float]) -> None:
    inner(*name_and_num)

Expected Behavior

arg-type error on line 14

Actual Behavior

No error on line 14

Your Environment

• Mypy version used: 1.5.1
• Python version used: 3.11.5

Beginne damit, das Verhalten mit dem bereitgestellten Beispiel mit fun1, fun2 und fun3 unter Python 3.11.5 mit mypy 1.5.1 zu reproduzieren. Verfolge den Type-Checking-Pfad für die entpackte Union-of-Tuples und überprüfe, dass der Aufruf in fun3 den erwarteten arg-type-Fehler in Zeile 14 meldet.
