克隆WooCommerce订单，加税，订单总额不包括费用

Question

我正在使用下面的 PHP 克隆 WooCommerce 订单。我的订单项匹配，我在下方看到一个税收项目（作为费用添加），相同的运费，相同的项目小计。但是，该费用并未添加到订单总额中，该金额恰好太低了。之后，woocommerce_order_items 和 woocommerce_order_itemmeta 中的条目看起来相同，请参见附件截图。

原始订单中的税额是这样添加的，使用 woocommerce_checkout_create_order 挂钩：

$order->add_fee('Tax', $tax_total);
$order->save();

下面是克隆订单的脚本。我怎样才能让订单总额更新为正确的金额，包括税（费用）？

    WC()->cart->calculate_totals();
    $order_id = $checkout->create_order( [ ] );

    $order->calculate_totals();

    $message = sprintf(
      'This order was duplicated from order %d.', $original_order_id
    );
    $order->add_order_note( $message );

    $order->payment_complete();

    $order->update_status( 'processing' );
