Will this result in any ax events?

[dmazzoni, 2016/10/26 16:20:22]

Yes, but the existing mechanism you added suppresses it from
speaking.

[David Tseng, 2016/10/26 17:03:26]

Great, so you didn't get any repeated text/odd focus syncing while navigating
with ChromeVox.

   getNode()->document().setSequentialFocusNavigationStartingPoint(getNode());
 }
