 I'm removing the nav menu panel contextually for a minimalist Customizer
 experience.

 If you remove the nav menu panel, the
 [https://github.com/WordPress/WordPress/blob/4.3/wp-includes/class-wp-
 customize-nav-menus.php#L340 l10n configuration breaks] because it
 directly attempts to get the title from the nav menu panel object.

  e.g.

 ```
 <?php
 add_action( 'customize_register', function($manager) {
         global $wp_customize;

         foreach ( $wp_customize->panels() as $key => $panel ) {
                 $wp_customize->remove_panel( $key );
         }

         foreach ( $wp_customize->sections() as $key => $section ) {
                 $wp_customize->remove_section( $key );
         }

 }, 50, 1 );
 ```
