gtkbox: Invalidate order on changes, even if the child is not visible

Browse Source 
When we build the sibling path for the order, we do not skip hidden
children (since, quoting the comment, "we cannot reliably detect changes
in widget visibility"). So we need to invalidate the order when hidden
children are reordered and removed.
