Comment on attachment 164549 [details] Patch View in context: https://bugs.webkit.org/attachment.cgi?id=164549&action=review Looks good! r=me with the below mistake fixed. (Perhaps we could even add a test for it?) > Source/WebCore/css/SVGCSSComputedStyleDeclaration.cpp:197 > case CSSPropertyMarker: > + case CSSPropertyMaskType: > + return CSSPrimitiveValue::create(svgStyle->maskType()); Beep beep! Mistake here: We shouldn't return the mask type for CSSPropertyMarker.
