Comment (by westonruter):

 This is related to a workaround I had to put in place for the
 `WP_Nav_Menu_Widget` to deep link to the menus panel from a given nav menu
 widget:

 {{{#!php
 <?php
 if ( isset( $GLOBALS['wp_customize'] ) && $GLOBALS['wp_customize']
 instanceof WP_Customize_Manager ) {
         // @todo When expanding a panel, the JS should be smart enough to
 collapse any existing panels and sections.
         $url = 'javascript: wp.customize.section.each(function( section ){
 section.collapse(); }); wp.customize.panel( "nav_menus" ).focus();';
 } else {
         $url = admin_url( 'nav-menus.php' );
 }
 ?>
 <?php echo sprintf( __( 'No menus have been created yet. <a
 href="%s">Create some</a>.' ), esc_attr( $url ) ); ?>
 }}}
