/// - cef_frame_handler_t::OnFrameAttached => The initial main frame object is
/// now connected to its peer in the renderer process. Commands can be routed.
///
/// (2) During further cef_browser_host_t navigation/loading of the main frame
/// and/or sub-frames:
///
/// - cef_frame_handler_t::OnFrameCreated => A new main frame or sub-frame
/// object has been created. Any commands will be queued until the frame is
/// attached.
/// - cef_frame_handler_t::OnFrameAttached => A new main frame or sub-frame
/// object is now connected to its peer in the renderer process. Commands can
/// be routed.
/// - cef_frame_handler_t::OnFrameDetached => An existing main frame or sub-
/// frame object has lost its connection to the renderer process. If multiple
/// objects are detached at the same time then notifications will be sent for
/// any sub-frame objects before the main frame object. Commands can no longer
/// be routed and will be discarded.
/// - CefFremeHadler::OnFrameDestroyed => An existing main frame or sub-frame
/// object has been destroyed.
/// - cef_frame_handler_t::OnMainFrameChanged => A new main frame object has
/// been assigned to the browser. This will only occur with cross-origin
/// navigation or re-navigation after renderer process termination (due to
/// crashes, etc).
///
/// (3) During final cef_browser_host_t destruction of the main frame:
///
/// - cef_frame_handler_t::OnFrameDetached => Any sub-frame objects have lost
/// their connection to the renderer process. Commands can no longer be routed
/// and will be discarded.
/// - CefFreameHandler::OnFrameDestroyed => Any sub-frame objects have been
/// destroyed.
/// - cef_life_span_handler_t::OnBeforeClose => The browser has been destroyed.
/// - cef_frame_handler_t::OnFrameDetached => The main frame object have lost
/// its connection to the renderer process. Notifications will be sent for any
/// sub-frame objects before the main frame object. Commands can no longer be
/// routed and will be discarded.
/// - CefFreameHandler::OnFrameDestroyed => The main frame object has been
/// destroyed.
/// - cef_frame_handler_t::OnMainFrameChanged => The final main frame object has
/// been removed from the browser.
///
/// Special handling applies for cross-origin loading on creation/navigation of
/// sub-frames, and cross-origin loading on creation of new popup browsers. A
/// temporary frame will first be created in the parent frame's renderer
/// process. This temporary frame will never attach and will be discarded after
/// the real cross-origin frame is created in the new/target renderer process.
/// The client will receive creation callbacks for the temporary frame, followed
/// by cross-origin navigation callbacks (2) for the transition from the
/// temporary frame to the real frame. The temporary frame will not receive or
/// execute commands during this transitional period (any sent commands will be
/// discarded).
///
/// When the main frame navigates to a different origin the OnMainFrameChanged
/// callback (2) will be executed with the old and new main frame objects.

/// 3. JavaScript 'onbeforeunload' handler executes and shows the close

/// 5. JavaScript 'onunload' handler executes.
/// 6. Application's TChromiumCore.OnClose handler is called and returns false (0) by

/// 7. CEF sends a close notification to the application's top-level window
