Black produced different code on the second pass of the formatter

[nikitakunevich]

To Reproduce

1. Run Black on this file:

def test_assembly_segment():
    assert assembly_segment(
        ResultSegment(
            result_ids=['9266515960', '9266515961', '9266515962', '9266515963', '9266515964'],
            result_mask_shares=[
                [7032960221190207203, 7525588980467272663, -560548502101970051, -4929818894735814806, -4917001310622507502],
                [-7032960221190141667, -7525588980467272663, 560548502102035587, 4929818894735814806, 4917001310622573038]
            ],
            segment_size=3
        )
    ) == ['9266515960', '9266515962', '9266515964']

2. See error "Black produced different code on the second pass of the formatter"

Hello!

All reproduction cases in this issue format without error on master. The fixing commit was 8672af3 from PR GH-2126. I'll be marking this issue as a duplicate of GH-1629 since that's what GH-2126 aimed to fix and it's highly likely this issue falls under GH-1629.

Since we use the issue tracker as a reflection of what's on master, I'll be closing this issue. If you have any issues, especially with the new (but stable) output, please open a new issue. Oh and the fix should be available in a published release soon, see GH-2125 for more info.

Thank you for reporting!
