Profile validation email generated by authorize.net doesn't include the customer email

Problem/Motivation

At some point the profile validation email generated by authorize.net was including an email address but since 8.x-1.0 was released the validation email just contain email@example.com. The error looks like https://community.developer.authorize.net/t5/Integration-and-Testing/CIM... but I am not sure if it's the same.

I am wondering if it has to do with the SDK or this module. I am wondering if this has something to do with the comment at https://git.drupalcode.org/project/commerce_authnet/blob/8.x-1.x/src/Plu...

// Due to their being a possible duplicate record for the customer
      // profile, we cannot attach the payment profile in the initial request.
      // If we did, it would invalidate the token generated by Accept.js and
      // not allow us to reconcile duplicate payment methods.
      //
      // So we do not attach a payment profile and run two requests, and make
      // sure no validation mode is executed.

Cause the email get generated after the initial request at line 667. The generated email looks like:
