Currently UiElementContainerView does not auto scroll when the focus in the AssistantCardElementView changes, e.g. during Tab traversing. This patch surfaces the OnFocusChangedInPage event from WebContentsImpl to NavigableContentsObserver, so that the UiElementContainerView can do scroll accordinglly. In this patch, if the bounds of the focused node is clipped by the container, it will scroll the node to the center of the container.
