Created attachment 266740 [details] Screenshot of incorrect rendering in WebKit Nightly Steps to reproduce: 1. Open https://bugzilla.mozilla.org/attachment.cgi?id=8665202 in WebKit Nightly Expected results: The yellow box should be entirely below (with respect to the Y axis) the blue floating box. See Chrome Canary screenshot. IE11 and Firefox Nightly also behave like Chrome Canary. Actual results: The blue floating box is entirely within the yellow box. See WebKit Nightly screenshot. Analogous Chrome bug: https://code.google.com/p/chromium/issues/detail?id=535381 Originally discovered in: https://bugzilla.mozilla.org/show_bug.cgi?id=1196255

Still broken in Tech Preview Release 13 (WebKit 11603.1.5). Worth noting that this was fixed in Chrome and the patch looks trivial: https://codereview.chromium.org/1393533002
