INTERNAL ERROR when using multiple fmt: skip

[BenjaminBossan]

Describe the bug

Using multiple # fmt: skip in the same expression causes an INTERNAL ERROR.

To Reproduce

The first example (a) works but all others fail:

a = (
    "this should "  # fmt: skip
    "be fine"
)

b = (
    "this is "  # fmt: skip
    "not working"  # fmt: skip
)

c = (
    "and neither "  # fmt: skip
    "is this "  # fmt: skip
    "working"
)

d = (
    "nor "
    "is this "  # fmt: skip
    "working"  # fmt: skip
)

e = (
    "and this "  # fmt: skip
    "is definitely "
    "not working"  # fmt: skip
)

The resulting error is:

INTERNAL ERROR: Black produced code that is not equivalent to the source

Expected behavior

The lines should be left untouched.

Environment

• black, 22.12.0 (compiled: yes)
• Python (CPython) 3.10.9
• Ubuntu 22.04

Can also be reproduced on https://black.vercel.app.

Additional context

Maybe I'm using fmt: skip incorrectly, but documentation on it is very sparse.

Maybe I got the same here:

error: cannot format serializers.py: INTERNAL ERROR: Black produced code that is not equivalent to the source.  Please report a bug on https://github.com/psf/black/issues.  This diff might be helpful: /var/folders/lg/s80890fd1ts6s1w69c8lg03m0000gn/T/blk_v5h775n6.log
