 // To ease modernizing the NTP only the internal panels are being converted
 // to UIViewControllers.  This means all the plumbing between the
 // BrowserViewController and the internal NTP panels (WebController, NTP)
 // hierarchy is skipped.  While normally the logic to push and pop a view
 // controller would be owned by a coordinator, in this case the old NTP
 // controller adds and removes child view controllers itself when a load
 // is initiated, and when WebController calls -willBeDismissed.
