[BUG]: Express Checkout Element errors with token_already_used if the user users a card with a failure followed by a card that should be successful

[mattbegent]

What happened?

When using the Express Checkout Element, Stripe is erroring with token_already_used if the user users a card that is declined first and then uses one that should succeed.

Steps to reproduce

1. Go to https://docs.stripe.com/elements/express-checkout-element?locale=en-GB
2. Click on the Google Pay button in the "Try the demo" section
3. Select the Generic decline Visa card
4. Click "Continue"
5. Change the payment method to GB Debit Visa card that should success, without closing the Google Pay overlay
6. Click "Continue"
7. The payment will not succeed and if you look in the network at the failure you will see the "token_already_used" error.

Expectation

Users are able to complete a transaction if they pick a card that fails and then one that should succeed.

Other notes

If the user repeats the above steps but closes the Google Pay overlay after the failure and then reopens it to select the successful card, then the transaction does go through.

Environment

Chrome 134.0.6998.166 and Windows 11
