// MimeHandlerViewEmbedder is instantiated in response to a frame navigation to
// a resource with a MIME type handled by MimeHandlerViewGuest. MHVE tracks the
// navigation to the template HTML document injected by the
// MimeHandlerViewAttachHelper and when the <embed>'s RenderFrameHost is ready,
// proceeds with creating a BeforeUnloadControl on the renderer side. After the
// renderer confirms the creation of BUC the MHVE will create and attach a
// MHVG. At this point MHVE is no longer needed and it clears itself.
// Note: the MHVE might go away sooner if:
//   - A new navigation starts in the embedder frame,
//   - the navigation to the resource fails, or,
//.  - the embedder or the injected <embed> are removed from DOM.
