Hi,
We are doing the following:
1. Create an order using v3/orders (See Sandbox Order ID: H4R6KHGGYG818)
2. Pay for order using ecommerce /v1/orders/{orderId}/pay (WF8HHB9HM2FYY for $107.26)
3. Refund #2 using /v1/orders/{orderId}/returns (JVPN6PNT0KBAE for $107.26)
4. Pay again for order using ecommerce /v1/orders/{orderId}/pay (04V2BP1MFT600 for $107.26 )
5. Refund #4 fails with "This refund would make the order's total refunded amount greater than the original order's amount."
I would expect 5 to succeed because, we did pay in at #4.
