            Bug ID: 234918
           Summary: REGRESSION(r285618):A crash may happen when
                    calculating the color-interpolation of a referenced
                    SVG filter
           Product: WebKit
           Version: WebKit Nightly Build

                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Layout and Rendering

When building a referenced SVGFilter, the color-interpolation property of the effect element is calculated. If the effect element does not have a renderer, we fallback to the computed style property value. If the filter is inside an <iframe> which has media queries, a Document::updateLayout() will be forced. Building the SVGFilter should not invoke an updateLayout() since this may not be safe and out of order.
