FetchError - Payment Intent Featch error unhandled

Problem/Motivation

Unhandled error resulting in occasional broken checkout flows. Users are not aware of Javascript error which is resulting in some abandoned carts.

We are observing sessions with the following JS errors:

(in promise) {"message":"Error fetching https://api.stripe.com/v1/payment_intents/[REDACTED]/confirm: Load failed","name":"FetchError","originalError":{},"requestUrl":"https://api.stripe.com/v1/payment_intents/[REDACTED]/confirm","type":"fetch_error"};

In some observations this caused the payment to fail but no message was presented to the user. After numerous failed attempts the carts were abandoned.

These payment errors should be caught and a relevant message displayed to the user.
