/* This protocol's primary use is so widget/cocoa can talk back to us
   properly.

   ChildView owns the topmost mozRootAccessible, and needs to take care of setting up
   that parent/child relationship.

   This protocol is thus used to make sure it knows it's talking to us, and not
   just some random |id|.
