Description Dominic Mazzoni 2012-07-23 23:19:54 PDT
This won't affect Mac, this is for the Windows and Chromium/Windows ports.

There are some ARIA attributes that are supposed to trigger a notification on Windows but they don't now. It's probably mainly the ones that are supposed to trigger a notification on Windows but not on Mac that are left. A possibly-incomplete list is: aria-busy, aria-disabled, aria-expanded, aria-invalid, aria-readonly, aria-required, aria-valuetext.

BRB: May be a dupe or resolved already. I know we did some Windows notifications work since the time this bug was filed.

This is also expected for ATK. I need to see which ones are missing still.

This is still a major problem for aria-expanded (using Voiceover 8.4/Safari).
When user activates a UI control and its aria-expanded attribute is updated Voiceover does not announce its updated state. Users have to swipe away from the element and back to it to be informed of the change.
To verify, interact with one of the expand/collapse buttons in this example:
