           Summary: SVGSVGElement::selfHasRelativeLengths probably can
                    return bogus results for width and height
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: SVG
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: krit at webkit.org

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.
