Testcase

Webkit apparently treats item() on form.elements and other HTMLCollections as an alias for namedItem if a string is passed or something.  This is wrong per the spec at http://www.whatwg.org/specs/web-apps/current-work/multipage/common-dom-interfaces.html#htmlformcontrolscollection as well as per the DOM 2 HTML spec.  See the attached testcase; it should say "PASS" twice.

BUILD: Current WebKit nightly.

STEPS TO REPRODUCE:
Load attached testcase.

EXPECTED RESULTS: 2 lines that say "PASS"

ACTUAL RESULTS: 2 lines that say "FAIL"

Gecko and Presto both get this right.
