Remarks
Use Cef.UIThreadTaskFactory to execute this method if required, Cef.OnContextInitialized and ChromiumWebBrowser.IsBrowserInitializedChanged are both executed on the CEF UI thread, so can be called directly. When CefSettings.MultiThreadedMessageLoop == false (the default is true) then the main application thread will be the CEF UI thread.
