 @sidati Hi, there aren't any plans to add a `widgets-ready` or `sidebars-
 ready` event. I don't see a use case for why it would be necessary. If you
 want to ensure that your code fires after widgets are initialized, you can

 wp.customize.bind( 'ready', _.defer( function() { /* your code here */ } )

 @Fab1en: Also, your original use case of wanting to focus on a control
 from the preview is not generally available by sending a message from the
 preview like this:

 wp.customize.preview.send( 'focus-control-for-setting', 'blogname' );

 Support for sending this message was added in [36586] for #27355 in the
 implementation of selective refresh. Shift-clicking on any partial
 registered for selective refresh will send this `focus-control-for-
 setting` automatically. But you can use it yourself manually outside the
 context of partials.
