I noticed that the details validation step doesn't pass an OperationError DOMException to the payment app failure algorithm, while the other validation steps (e.g., methodName, shippingAddress, payerName, etc.) all do.
Was this intentional, or just accidentally missed? Let me know if there's a reason for treating it differently — I might be missing some context.
