           Summary: HTMLCollection.item should not return elements by
                    ID/name
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: HTML DOM
        AssignedTo: webkit-unassigned at lists.webkit.org

Currently, the implementation of item(unsigned long) looks at the ID/name of elements in the collection if the argument isn't an integer, for some value of integer. [1,2] WebIDL, [3] however, requires that the argument is converted into an integer by ToNumber, which returns NaN for normal strings, and then ToUint32, which is 0. So item("foo") should return the first element in the collection.
