If the item is a UIElement with its own peer as reported by Owner, then information from that peer is forwarded. Next, the container peer (which could be ItemsControlAutomationPeer, ListBoxAutomationPeer, or another class) is used as a possible source. Finally, if there is no container peer, then this method returns true.
