Issue

Discount is incorrectly applied to a bundled child product.

Steps to reproduce:

1. Create a simple product with price of 50$.

2. Create a bundled product, and assign the simple product as the only option for the bundled product.

3. Create a Cart Price Rule with:

   • Condition: If the total amount is greater than 130$
   • Action: Fixed amount discount of 10$ is applied

4. Go to the storefront and add the bundle product to the cart with qty = 1.

5. Go to the cart and check that the total cost of the bundle product is 50$ and the discount doesn't apply.

6. Change quantity to 2 and update the cart. The total cost of the bundled product should now be 100$.

Expected results:

The discount is not applied because the subtotal is 100$, which is less than 130$ in the rule condition.

Actual results:

The discount is applied.
