Stock not updated

When creating a order by code like this

$checkout = WC()->checkout();
$customer = new WC_Customer( $current_user_id );
$order_id = $checkout->create_order( [
  'billing_email'  => $customer->get_billing_email(),
  'payment_method' => "sepa",
] );

The default stock quantity is not updated because in class-slw-order-item.php the $current_page is checked. I have now a workaround to set the $current_page, but its maybe better to implement the hook woocommerce_checkout_order_created
