Removing strip_tags not working on nav_menu_description

in a new wordpress version, the remove_filter isn’t enough, cause the desc is stripped hardcoded from post_content …

this will do the trick:

remove_filter('nav_menu_description', 'strip_tags');
add_filter( 'wp_setup_nav_menu_item', 'cus_wp_setup_nav_menu_item' );
function cus_wp_setup_nav_menu_item($menu_item) {
                $menu_item->description = apply_filters( 'nav_menu_description',  $menu_item->post_content );
                return $menu_item;
}
