PayPal - c.FUNDING undefined is not an object

[Vasyl-ParkulabOSF]

Describe the bug
In our Salesforce PWA application we are encountering the error:
TypeError: undefined is not an object (evaluating 'c.FUNDING')
Which is similar to the #2385
I have also checked on https://adyen-salesforce-pwa-demo.mobify-storefront.com/ and I can reproduce it there also
To Reproduce
Steps to reproduce the behavior (for https://adyen-salesforce-pwa-demo.mobify-storefront.com/):

1. Add a product to the cart, fill billing / shipping information, select shipment option.
2. On Payment step - select Paypal and on pop-up window select option "return to portal" or just close the paypal window.
3. Add a new product to the cart and perform step 1 again.
4. Select Paypal option - button is not visible and the error in console is present (paypalReference is empty)

Expected behavior
Button to be present on further checkout attempts.
