Thank you @HazardyKnusperkeks for the review.

@owenca I agree — I also don't see why anyone would want the current behavior, so it definitely seems like a bug to me as well.
It's absolutely possible to fix this without introducing a new option: the check I wrote could simply apply unconditionally when ``BinPackParameters`` is set to ``AlwaysOnePerLine``.

If we take that approach, most of the changes in the PR would also become unnecessary.

Let me know how you'd like to proceed, and I’ll update the patch accordingly.
