Microdata: names.item() must return null for out of range indexes. https://bugs.webkit.org/show_bug.cgi?id=97898 Reviewed by Kentaro Hara. Source/WebCore: DOMStringList.item() must return null for an invalid index. Spec: http://www.w3.org/TR/DOM-Level-3-Core/core.html#DOMStringList Removed [IsIndex] extended IDL attribute from item() method's index parameter in DOMStringList interface. Firefox and Opera's behavior is consistent with the spec. Both returns null for invalid index.
