Addition of type ignore causes undesirable splitting on another line

[hauntsaninja]

This is the original version of the code:

Playground

def one():
    def two():
        def three():
            _zzzzzzz_zzzz_zzzz_zzzz(
                zzz.getZZZZZZZZZZZZZZZZZ("zzz_zzz_zzzz_zzzz")[0].getZZZZZZZZZZZZZZZZZ(
                    "zzzzzzz_zzzz_zzz"
                )[0]
            )

Black is quite content with this.

However, if you add a # type: ignore on line 5:

Playground

def one():
    def two():
        def three():
            _zzzzzzz_zzzz_zzzz_zzzz(
                zzz.getZZZZZZZZZZZZZZZZZ("zzz_zzz_zzzz_zzzz")[0].getZZZZZZZZZZZZZZZZZ(  # type: ignore
                    "zzzzzzz_zzzz_zzz"
                )[0]
            )

Black suddenly wants to split line 7:

def one():
    def two():
        def three():
            _zzzzzzz_zzzz_zzzz_zzzz(
                zzz.getZZZZZZZZZZZZZZZZZ("zzz_zzz_zzzz_zzzz")[0].getZZZZZZZZZZZZZZZZZ(  # type: ignore
                    "zzzzzzz_zzzz_zzz"
                )[
                    0
                ]
            )
