CSSStyleDeclaration CSS property getters and such are defined to be WebIDL attributes: * https://drafts.csswg.org/cssom/#dom-cssstyledeclaration-_camel_cased_attribute WebKit (and Blink) implement it using item(), which is not quite the same, since checks like hasOwnProperty return true for the later but not for the former.
