Placing order with Klarna, Clearpay payment through GraphQL removes cart before payment is completed (Plugin v9)

[rcbello]

Describe the bug
In a headless implementation using graphql, calling placeOrder mutation on cart with Klarna or Clearpay payment makes it inaccessible even before payment is completed or adyenPaymentDetails mutation is called.
After placeOrder mutation, calling cart query with cart id returns 'Cart is inactive' error. And, calling customerCart returns a new empty cart.
Calling adyenPaymentDetails with payment data, order number and cart id also results in inactive cart error, so payment cannot be completed.
This doesn't happen for Paypal or Credit Card with 3DS2 which follow the same flow.

To Reproduce
Steps to reproduce the behavior:

1. Prepare a customer cart for payment, add product, set shipping address, shipping method and billing address.
2. Call setPaymentMethodAndPlaceOrder with klarna or clearpay payment method, and placeOrder in a single graphql mutation.
3. placeOrder response will be an order with isFinal=false and additional action that needs to be completed. Order with pending status will be created.
4. Complete payment by calling adyenPaymentDetails with action result, order number, and cart id.
5. 'Cart is inactive' error will be returned. And, original cart will be inaccessible.

Expected behavior
Original customer cart should still be accessible and payment can be completed by calling adyenPaymentDetails mutation.

Magento version
2.4.6-p2

Plugin version

Additional context
We're using graphql api for our native iOS and Android apps.
Doesn't happen for Adyen Paypal payment method and Klarna used to work in plugin v8.
