Bug 121408 – AX: ARIA tablist is disabled, but VoiceOver does not speak the tabs as dimmed

• Status: RESOLVED
• Resolution: FIXED
• Component: Accessibility

[chris fleizach]

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.

The const_cast is needed, but the static_cast is not.
