problem with Stripe payment processor when registering multiple participants

[Upperholme]

Using 4.5.8 I'm setting up an event with a price set. I want to enable users to register multiple participants, and I'd like to use the Stripe payment processor, which is working well for me with webforms.

Testing the set up I see that the payment processor puts its fields on the first page of the registration form, so I can only enter details and price options for the first participant. If I ignore the payment fields and try to continue to the second participant I get stopped by the required field validation on the billing fields.

Surely the payment fields should be at the end of the registration form?

Or am I missing something.
If I swap to using Paypal standard as my payment processor things seem to work fine.

I raised the issue with Joshua - the Stripe processor developer, and he said that this is outside the scope of the processor, it just plugs in like any other payment processor.

Anyone got Stripe working in a context where the user can register multiple participants?
