Column spans and multi-column elements should establish block formatting contexts. They mostly do except for the part where they should not be collapsing margins with their children. This bug is about fixing the margin collapsing issue.

Fixed in r91497. A bunch of multicol tests will need to be rebaselined. I'm on Lion so can't do SL.

Should '-webkit-column-count:0' establish a block formatting context and prevent margin-collapse through ? It does with the latest nightly (r91611) on Snow leopard. The spec says: "Values must be greater than 0" http://dev.w3.org/csswg/css3-multicol/#cc Opera 11.5 does not establish a BFC - the margins of the child element collapse through (unless of course the multi-col element has a border) testcase: http://dev.l-c-n.com/CSS3/multi-col/multicol-bfc3.html
