 I installed a plugin that register_post_type with menu_position 80.
 Thereafter, I installed a plugin to add a menu by add_utility_page. Then
 the menu of menu_position 80  is disappeared.

 Where I examined, I think there is a problem with the count up of
 `$_wp_last_utility_menu`, but is this correct specification?

 This is the sample code.

 {{{
 function test_add_utility_page() {
     add_utility_page(
         'test_utility_page',
         'test_utility_page',
         'edit_posts',
         'test_utility_page',
         '__return_false'
     );
 }
 add_action( 'admin_menu', 'test_add_utility_page' );

 function test_register_post_type() {
     register_post_type( 'test_post_type', array(
         'labels'        => array(
             'name' => 'test_post_type',
         ),
         'public'        => true,
         'menu_position' => 80,
     ) );
 }
 add_action( 'init', 'test_register_post_type' );
 }}}
