Reviewed by Chris Fleizach.

This change fixes aria-selected-menu-items in isolated tree mode by adding a traversal up for the newly selected child so that its ancestor
also updates its SelectedChildren property.
The traversal happens during a new case in AXObjectCache::updateIsolatedTree where the notification AXMenuListItemSelected is now handled.
