The SVG in the link has following example:
<g fill="currentColor" color="red">
<rect x="120" y="60" width="150" height="150" color="blue"/>
Our current implementation inherits the 'fill' property of the <g> element: 'currentColor'. Our PaintServer see the value 'currentColor' for 'fill' on drawing the rect. It takes the value in 'color' of the rect, instead of the <g> element. This is not the expected behavior.
The relevant code is here: http://trac.webkit.org/browser/trunk/WebCore/rendering/RenderSVGResource.cpp#L97
The same issue for stroke.
