Original issue's description:
> Android accessibility: automatically focus links
>
> When setting accessibility focus to a node, auto-focus it if it's a link.
> This is needed for some sites that have skip links that are only visible
> when focused. It might be possible to auto-focus more than just links but
> this seems the safest.
>
> Fixing this exposed a race condition with our code to refocus the node with
> accessibility focus if its location has changed - essentially when you
> click on the skip link, the skip link was changing its location, causing us
> to fire notifications on it because its location had changed - but that
> was racing with the real change to accessibility focus from following the
> skip link.
>
> Fix this race condition by re-focusing the node with accessibility focus
> after a short delay, and canceling the delayed task if accessibility
> focus changes again.
>
> Tested manually with two urls that exercise these code paths.
