Answer need little modifications. Remove the function get_attribute_highlighted() and replace this line

   $value = get_attribute_highlighted($attribute->get_name(), $i);
    

TO

    global $post;
    $post_id = isset($_POST['post_id']) ? absint($_POST['post_id']) : $post->ID ;
    $value = get_post_meta($post_id , "attribute_description".$i, true);

It will show ajax saved value instance of empty;

And Change hooks

add_action('wp_ajax_woocommerce_save_attributes', 'wcb_ajax_woocommerce_save_attributes', 10);

TO

add_action('wp_ajax_woocommerce_save_attributes', 'wcb_ajax_woocommerce_save_attributes', 0);
