Comment on attachment 20361 [details] Patch and test for the bug. r=me Looks exactly right. (Actually it would be even better if the test covered ry as well as rx but that would be optional.
Oh, funny bug. Good you noticed. Exactly because of bugs like that the plan was to fill svg/dynamic-updates/SVGXXXElement-svgdom-xxx-prop.js / etc. with life. Unfortunately we're still at SVGGElement, and it's a long way to SVGRectElement :-)
