Do these need to be virtual?

[meade_UTC10, 2016/01/19 00:15:19]

I don't think so - The idea is that the CSSPropertyID versions are virtual, the
string ones just delegate to the PropertyID ones, so they shouldn't need to be
(and I've now updated the rest of the methods to follow this pattern). Is there
a usual convention for that kind of thing in blink?

Latest patch seems fine for this.

+{
+    return get(cssPropertyID(propertyName));
+}
+
+void StylePropertyMap::set(const String& propertyName, StyleValueOrStyleValueSequenceOrString& item, ExceptionState& exceptionState)
+{
+    return set(cssPropertyID(propertyName), item, exceptionState);
+}
+
+} // namespace blink
