With a non-visible overflow, you are correct: there is clipping or
scrolling. But with overflow: visible, this is not what is observed, at
least with abs. pos. (replaced and/or non-replaced) elements

Anyways... I am confortable with whatever decision is taken with regards
to multi-column element and column boxes in that issue. :)



I've checked the §10.3.8 tests


we have:






and they are all under 100% of the containing block's width.
I think we need now at least one test where the abs. pos. replaced element
width is set to over 100% of the containing block's width.
