           Summary: Enumerating an HTMLCollection needs to enumerate the
                    named properties
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: HTML DOM
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: bzbarsky at mit.edu

Consider this testcase:

<!DOCTYPE html>
<form id="x">
<script>
for (var x in document.forms)
  document.writeln(x);
</script>

EXPECTED RESULTS: "0 x item namedItem length" in some order

ACTUAL RESULTS: "0 length item namedItem"

Note the missing 'x'.

Gecko and Presto get this right.  Trident in IE9 enumerates the 'x' but not the '0', as far as I can tell.
