Yeah, I completely agree that @mstensho 's model in that comment is the right one, and very strongly advocate that it be folded into the spec, as the CSSWG resolved. The only question here is about how we capture the way that it's taken out of the columns' fragmentation flow and formatted as a sibling of the column row boxes. Initially the idea was to treat it as a block-in-inline split situation; however dbaron was arguing it should be out-of-flow because then there doesn't need to be some abstract tree structure representing all of the boxes between it and the multi-column container, since that's complicated to implement. I think either concept is good enough, but yes, we should be clear about the effect on the painting order. Probably column spanners should interleave with the row boxes the same as other in-flow content; I guess its an interesting question whether they should form a pseudo-stacking context (like inline blocks) or behave like regular block boxes.
