CSS.supports.length is 2 instead of 1. There are two methods in the IDL: Source/WebCore/css/DOMCSSNamespace.idl interface DOMCSSNamespace { static boolean supports(DOMString property, DOMString value); static boolean supports(DOMString conditionText); }; The final length should probably be the shortest length of all same-name functions.

CSS.supports.length is 1 in WebKit ToT...
