Black adds unexpected trailing comma in return type wrapped in parenthesis

[yilei]

Code before:

def asdf_asdf_asdf_asdf_asdf() -> my_module.Asdf | my_module.AnotherType | my_module.YetAnotherType | None:
    pass

Black formatted to:

def asdf_asdf_asdf_asdf_asdf() -> (
    my_module.Asdf | my_module.AnotherType | my_module.YetAnotherType | None,
):
    pass

The trailing comma is incorrect, see playground.
