The Mac accessibility impl should defer to BrowserAccessibilityManager

to determine if a node has focus, not the element's state (which goes
stale too quickly - that's how we enforce that only one element is focused
at once). That was preventing VoiceOver from notifying us when it wanted to
set focus, because it thought a node already had focus when it didn't.

BUG=105923
TEST=Use Chrome with VoiceOver, use VoiceOver navigation keys to browse focusable elements repeatedly.
