WebKit does not support DOM Level 3 custom events, required by WICD tests http://www.w3.org/2004/CDF/TestSuite/WICD_CDR_WP1/test-custom-event.xhtml
Hmm, the problem I can see with this test is that the radio button is not selectable, even manually. If I add a name attribute to the button, the tests works.
Supposedly Firefox and Opera "pass" this test... so perhaps our selection criteria are wrong. I wonder what IE does.
I added a name attribute to the input element. Looks green to me. Bug resolved (test was invalid).
Filed bug 16337 for the radio button issue.
