[BUG]: defaultValues and fields configuration ignored if Payment Element is initialised without Payment intent

[tomswales]

What happened?

In the API docs for Payment Element, it mentions the defaultValues and fields options for prefilling or hiding fields in the Payment Element. This works for a Payment Element initiated with a Payment Intent already created, but not for a Payment Element initiated with no Payment Intent already created. The prefilled fields and hidden fields provided are simply ignored. For example:

defaultValues: { billingDetails: { name: "My Name", email: "tom@example.com" } }

Has a different outcome depending on whether the payment intent was created or not:

Is it intentional? There are valid use cases for initiating the Payment Element with prefilled fields even where we don't want to create an intent yet.
