           Summary: Make namedItem return a node list only in
                    HTMLFormControlsCollection and HTMLOptionsCollection
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified

         Component: HTML DOM
        AssignedTo: webkit-unassigned at lists.webkit.org

DOM4 and HTML5 specifications make HTMLFormControlsCollection and HTMLOptionsCollection’s namedItem and named getter return a node list when there are multiple matches.

However, by default HTMLCollection’s namedItem and named getter returns the first item that matched the name, and this behavior can be much more efficient since it can stop the search as soon as it finds the first match. We should introduce the former two interfaces (they’re currently both implemented as HTMLCollection in WebKit) so that we can confine the said obnoxious, inefficient, behavior to those two interfaces.
