Wrong return total when combining item and order discounts

Description

Precondition:
There are 3 promotions

• Buy 3 fashions at fixed price, $100 (first priority).
• Buy 3 fashions, get 1 cheapest free (second priority).
• Buy 3 fashions, get $10 off on order ( third priority - order discount type).

Steps to reproduce:

1. Place order with 3 Puma Red (unit price $52.50) => All 3 promotions are applied.
   • After the first promotion, 3 Puma Reds have a price $100.
   • After the second promotion, 3 Puma Reds have a price of $66.67.
   • After the third promotion, 3 Puma Reds have a price $56.67.
   • => With a shipping cost of $20, the order total is $76.67.
2. Complete the order.
3. Create a return of 1 Puma Red.

Expected: After returning 1 puma red, all discounts are invalidated. The remaining 2 puma reds have a price of $105 => Return total should be $0.

Actual: Return total is $38.33.
