Comment:

 @mdifelice as of 4.7 there's actually a facility for this. Namely, the
 `wp.customize.state( 'previewerAlive' )` value. See
 https://github.com/WordPress/wordpress-
 develop/blob/c321e10c1642fabed623292d1d157d341662b7d9/src/wp-admin/js
 /customize-controls.js#L3888-L3936

 So what a patch here could look like is:

 {{{#!js
 wp.customize.state( 'previewerAlive' ).bind( function( isAlive ) {
     if ( isAlive ) {
         // Hide notification.
     } else {
         // Show notification.
     }
 });
 }}}

 The notification could be displayed via #35210.
