Description Dirk Schulze 2014-05-18 02:32:24 PDT 
width and height are presentation attributes and can be set in an style sheet. Setting the style in a style sheet does not affect the presentation attribute style. SVGSVGElement::selfHasRelativeLengths currently checks baseVal of width and height on the presentation attribute style only. It must check the computed value instead.

The problem: selfHasRelativeLengths does not depend on RenderObjects at the moment. Since width and height are computed in RenderStyle, we probably should move this whole logic to RenderObject (the individual renderers) somehow.

I am not sure on whether this is still present or not but just wanted to share the code path, appreciate if someone can have a look. Thanks!
