[Stripe SCA] Backoffice orders: Can't capture second stripe payment

[drummer83]

Description

As a consequence of #5574, orders with a stripe transaction fee end up with a balance due. However trying to pay this with a second stripe payment fails (for unknown reason to me). The failing payments do not even show up in Stripe's backend.
Also the payment cannot be deleted from the payments list (see flash message in the screen capture).

Note: Splitting a stripe payment into 2 or more pieces by adjusting the amount to be paid by the first payment, seems to work fine.

Expected Behavior

Additional backoffice payments with stripe should be possible at all times.

Actual Behaviour

The second payment to cover the balance due with stripe is failing.

Steps to Reproduce

As shop owner :

1. Set up a stripe payment method with a payment fee.
2. Create a backoffice order using that payment method - observe the 'balance due' as a consequence of [Admin][Order] "Balance due" state after payments with a transaction fee #5574.
3. Try to capture a second stripe payment with the amount of the 'balance due' - observe the payment being listed as failed in the payments list.
4. Try to void the failed payment - observe the flash message at the top of the screen.

Hmmm, I just did this on v4.2.38 and it worked fine.
