 * were calculated based on the order item unit price, which was the default
 * logic prior to Commerce 2.8, changed in #2980713.

 * Adjustments are always displayed in the order total summary, below
 * the subtotal. They are not shown as a part of the order item prices.
 * To get the order item total price with adjustments included, use
 * $order_item->getAdjustedTotalPrice().
