Margin collapsing is a document-oriented feature. For applications it just causes confusion and slowness. margins.sky has failure output because offsetTop is returning the wrong values. That's not new with this patch though. When I look at it visually in skydb, everything seems to be in the right place. R=esprehn@chromium.org Review URL: https://codereview.chromium.org/700743002
