Original bug: http://code.google.com/p/chromium/issues/detail?id=162628 777015 1 ap 2012-11-27 11:25:29 -0800 Is it known when this regressed? It fails even in Safari 6.0.2. 777210 2 krit 2012-11-27 14:09:20 -0800 Philip, does this just happen with inline SVG? Does it just happen with SVG root elements? I think we have a lot of tests for pure SVG covering this. So it might be a problem between HTML and SVG. 778476 3 pdr 2012-11-28 16:30:53 -0800 I think this may be caused by the supremely confusing fact that style="width:x" and width="x" are different. For the most part, this affects the svg/html boundary and is present on <svg>. 778832 4 pruzand 2012-11-29 02:00:06 -0800 (In reply to comment #1) > Is it known when this regressed? It fails even in Safari 6.0.2. [for the log: I'm the one who filled the original chromium bug, working on Dojo Toolkit dojox/gfx api). From my tests, and using the webkit number as it appears in the browser user agent, it looks like the problem appears for webkit version > 534 (AppleWebKit/534.x ). 536 and 537 have the problem, 534 don't. 779511 5 pdr 2012-11-29 15:32:06 -0800 (In reply to comment #4) > (In reply to comment #1) > > Is it known when this regressed?

You're right that this is a regression after all. I looked into this further and did a bisect on the chromium tree. I think the regression range is: https://trac.webkit.org/log/?verbose=on&stop_rev=105127&rev=105862&limit=10000 There are two likely regressees: https://bugs.webkit.org/show_bug.cgi?id=76447 https://bugs.webkit.org/show_bug.cgi?id=76446 Assigning this bug to myself. 780856 6 177132 pdr 2012-12-01 23:36:18 -0800 Created attachment 177132 Invalidate SVG width on width attribute changes. 781689 7 177132 krit 2012-12-03 11:22:45 -0800 Comment on attachment 177132 Invalidate SVG width on width attribute changes.

I don't think so because this bug is about the root element, whereas 99996 is a drop shadow element. I haven't run the tests to verify this though. 809093 14 krit 2013-01-16 22:42:00 -0800 (In reply to comment #12) > Philip, could bug 99996 be a duplicate of this as well? Definitely not. The problem is that FilterFunctions don't have a renderer and don't react correctly on style changes. Everything else is just a hack. 176088 2012-11-26 15:24:50 -0800 2012-11-26 15:24:50 -0800 Testcase seta.html text/html 1157 pdr
