[Bug] Debit or Credit Card section not loading after click the button

Library used

paypal-js

🐞 Describe the Bug

When clicking the Debit or Credit Card button too quickly after the page loads, the credit card page fails to load. It's very intermittened but I can see that the error stems from a HTTP 400 error coming back from /smart/card-fields endpoint when the SDK tries to render the credit card iframe.

This issue is reproducible on your demo checkout page here: https://developer.paypal.com/demo/checkout/#/pattern/validation

🔬 Minimal Reproduction

1. Navigate to https://developer.paypal.com/demo/checkout/#/pattern/validation
2. As soon as you see the black Debit or Credit Card button appear, click it

Please note that it doesn't happen all the time. I often have to try multiple times before I'm able to reproduce it.

😕 Actual Behavior

Spinner appears and spins endlessly

🤔 Expected Behavior

Spinner should appear briefly while it loads the credit card form but then it should disappear and the form should be visible.

🌍 Environment

• Node.js/npm: -
• OS: - Windows
• Browser: - Chrome (latest)

I have the same problem, it seems to be only happening on Sandbox account and is also country-specific. It started to appear consistently (although not on every test) about a month ago.

We have also encountered the same problem. Do you have a good solution? Or reduce the probability of interface errors?
