 // An AdViewGuest is a WebContentsObserver on the guest WebContents of a
 // <adview> tag. It provides the browser-side implementation of the <adview>
 // API and manages the lifetime of <adview> extension events. AdViewGuest is
 // created on attachment. When a guest WebContents is associated with
 // a particular embedder WebContents, we call this "attachment".
 // TODO(fsamuel): There might be an opportunity here to refactor and reuse code
 // between AdViewGuest and WebViewGuest.
