When a tablist is disabled, but VoiceOver does not speak the tabs as dimmed http://www.w3.org/WAI/PF/aria/complete#aria-disabled "The state of being disabled applies to the current element and all focusable descendant elements of the element on which the aria-disabled attribute is applied." According to that, I think the safest thing to do would be to have WebKit expose AXEnabled: NO on the descendant elements as well. The current explicit "AXEnabled:YES" seems wrong. <rdar://problem/13634680>
