Modal checkout clones the Woo order review table and sticks it at the bottom of the modal whenever WC checkout updates. However, in some cases it's possible for Woo to block the form before our cloning takes place, resulting in a blocked order review table:

This PR forces the cloned order review table to unblock prior to rendering it so this doesn't happen anymore:

How to test the changes in this Pull Request:

1. As an admin enable taxes or shipping and create a product that has these applied
2. Add a checkout button block to any page or post for the product in step 1
3. As a logged out reader, trigger modal checkout via the checkout button added in step 2
4. Register an account, and proceed to the checkout modal
5. Add billing details and select next
6. In the payment method step, confirm the order review table is not blocked

Bonus: Smoke test the order review table in other scenarios, such as updating the price via NYP, adding a coupon, etc.

This looks good! I tested a subscription product, a product needing shipping, plus NYP and coupon, plus the Donate block 👍
