Created attachment 212474 [details] patch to delete the expected png(s) and to add the -expected.html file When there's a <p> inside <div style="flow-into:flow">, the margins of the paragraph should collapse with the parent div but they don't. The LayoutTests/fast/regions/flow-content-basic.html test can't be turned into a ref test. The current expected png results are not correct. This bug blocks bug #120457.

This bug is invalid because: 1. In CSS, the adjoining margins of two or more boxes (which might or might not be siblings) can combine to form a single margin. Two margins are adjoining if and only if both belong to in-flow block-level boxes that participate in the same block formatting context ( http://www.w3.org/TR/CSS2/box.html#collapsing-margins ) 2. CSS Regions establish a new block formatting Context. ( http://dev.w3.org/csswg/css-regions/ )
