Yes, the instance is the same (within the session at least) - the
child is held in an instance variable which is initialised in
#initialize and otherwise doesn't change.

For simplification, let's say I have a MainComponent (which
canBeRoot), with children HeaderComponent, ContentComponent, and
FooterComponent. From what you say, should I expect to have only the
child component that calls #lightbox: to be "wrapped" and display the
lightbox? What about the case I mentioned where #lightbox: was sent by
the parent component?
