Bug 149544 – Make custom properties store the parser value list for variable resolution

• Component: Layout and Rendering
• Status: RESOLVED FIXED

[Dave Hyatt]

Refactor custom property parsing so that we hold the actual CSSParserValueList of parsed terms, functions and operators. This will allow us to iterate directly over the already-parsed terms, functions and operators when we do variable resolution.

Can't all this use customPropertyValue?

Something like

RefPtr<CSSValue> propertyValue = this->customPropertyValue(propertyName);
return propertyValue ? propertyValue->cssText() : emptyString();
