Re: [csswg-drafts] [css-gaps-1] Gap intersection point definition might need updating for multi-col (#12084)

I'm currently updating the multi-column model section in the level 2 spec to deal with rows caused by block direction overflow. 

There's a diagram in this comments which shows how the parts go together https://github.com/w3c/csswg-drafts/issues/11976#issuecomment-2753981259

So, in the block direction any gap decorations and so on would only be applied between multicol _rows_ and not for any _lines_ created by spanners. It's correct that you would want to break to account for the spanner and any margin applied to it, I think.

Something to bear in mind is that authors would like to be able to have `column-span: <integer>` to have a spanner that partially spans the multicol container. This is likely to be most useful at the top or bottom of a container, but it's worth bearing in mind that it could happen in future.
