So, what I really meant is how applications like Orca use the ATK APIs. If
there's any chance than get_parent would be called before ref_child then the
patch is wrong, as get_parent would return NULL. AFAIK WebKit constructs the
DOM tree when the page is loaded, and the a11y tree is constructed on-demand
when the a11y APIs are called.

But since you think the patch is wrong anyway we'll clear the queue.
