Follow-up from bug 16273. Steps to reproduce: 1. Open the bug URL. 2. Try to click the radio button. Results: it is highlighted on mouse down, but never triggered. Works in Firefox, works in Safari 2.0.4, fails in Safari 3.0.4 and TOT.
<rdar://problem/5635196>
Fails in the earliest WebKit nightly build, r11976, with Safari 2.0.4 (419.3) on Mac OS X 10.4.11 (8S165).
It seems this is done for winIE compability, see line 1047 of HTMLInputElement: 1047 return 0; // Match WinIE and don't allow unnamed radio b uttons to be checked. 1048 // Checked buttons just stay checked. See also test fast/forms/radio_checked_name.html. Cheers, Rob.
INVALID then.

I'm not sure this is really the correct behavior for XHTML... maybe. I guess we should make sure this is part of the HTML5 spec.
Adding Hixie for comment on Comment #6.
IE8 doesn't do this, so I'm not going to make the spec say to do it either. Mozilla and Opera don't do it.
