prompt session surfaces are added to its parent session's
promptSurfaceList only in Session::addChildSession. And that's called
only once per prompt session.

Once the once-blank has drawn its first frame it's moved to the
Session's surface list. But that move doesn't affect the surfaces own
promptSurfaceList.
