Describe the style change

I'm looking at differences between 22.8.0 and 23.1a1 on our code base, most of it looks really good ❤️ as always thanks for the great work

however there is one pattern of change that doesn't seem ideal, it's possible this has been flagged already, I wasn't sure what to look for.

22.8.0

            common.models.DateTimeField: (
                datetime(2020, 1, 31, tzinfo=utc) + timedelta(days=i)
            ),

23.1a1

            common.models.DateTimeField: datetime(2020, 1, 31, tzinfo=utc) + timedelta(
                days=i
            ),

when a line needs breaking there must be some logic to decide where to break it, I guess it will find multiple candidates and rank them somehow, it looks like in this case it's started favouring the later break, whereas before it was favouring the structurally more significant one
