However, certain elements which establish block formatting contexts may also satisfy those stated conditions and yet still do not collapse their margins as described (as can be deduced from the adjacency/collapsing rules). So those four items need to be qualified to exclude BFCs. Conversation begins: Bug description: http://lists.w3.org/Archives/Public/www-style/2011Mar/0425.html (#2)
