 // A WebViewGuest is a WebContentsObserver on the guest WebContents of a
 // <webview> tag. It provides the browser-side implementation of the <webview>
 // API and manages the lifetime of <webview> extension events. WebViewGuest is
 // created on attachment. That is, when a guest WebContents is associated with
 // a particular embedder WebContents. This happens on either initial navigation
 // or through the use of the New Window API, when a new window is attached to
 // a particular <webview>.
