Can create a submitted order with total not matching items associated with order

[TWarszawski]

When a customer adds a product to their cart while checking out, the order total may not accurately reflect the products in the order.

Steps to reproduce:

1. Start demo site, create a customer, create/pick test product.
2. Have the customer add the product to the cart and go through checkout up until the submit order step.
3. In a separate tab or window, log in again as the customer go to the cart page.
4. Update the quantity in the cart.
5. Finish checkout (click the Submit Order button).

Expected Result:
The order total matches the sum of the totals for each item in the cart.

Actual Result:
The order total reflects the total of the original items in the cart, but when examining the order page the updated items are shown to be associated with the order.
