Conflict of custom post type menu and add_utility_page

[inc2734]

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' );

Seems like a duplicate of #18622 which is currently marked as a duplicate of #16856, though I'm not sure I agree with that.
