Re: [csswg-drafts] [css-grid-3][masonry] Effect of negative bottom margins on running position + dense-packing (#13164)

One additional question to add on to this one:

If a negative `margin-bottom` effectively adjusts the block size of an item (up to 0px) with respect to the running position, does a negative `margin-bottom` also impact what openings are valid/can fit an item when that item is being densely packed (or is the `margin-bottom` only applied after the item is placed, meaning we only consider slots that would hold an item ignoring any negative `margin-bottom`)
