Admin refund reason is not saved

[novoselt]

When doing an admin refund, there is a list of reasons with the default "Requested by customer". I can select "Duplicate", but when confirmed, the record both in CoCalc and in Stripe is that it was "requested by customer" anyway.

Would be nice to have and my guess is that it should be easy - likely the code is there but something is missing in it.
