question: do we ever care that the previously focused item still has it's
focused state set?

[dmazzoni, 2011/11/30 22:02:27]

This change means that we're basically ignoring what state WebKit has set for an
object. BrowserAccessibilityManager keeps track of which item has focus and at
any instant in time, only one object will have the focused bit set when the AT
queries it.

   return ret;
