Previous button behavior like submit button

Problem/Motivation

When using a multistep form and the ajax option in the form is enables, if you try to go back to the previous page, the previous page button behavior is like the submit button

Steps to reproduce

Create a multistep webform, go to the payment step and try to go back to the previous page.

Hi, seems like the problem is in the stripe-webform-payment-ajax.js file since the beforeSend behavior is altered.
