Correct me if I’m wrong. It looks like Shopify before had just hardcoded an iframe to each page, which was ok, but became a problem since Google handled it the way it did. The iframe itself seems to be the same.
But with this solution an extra step is made. The iframe is not injected directly into the code. Asynchronous JavaScript is loaded. You can find in your source code now, which injects the iframe.
Disallow: /cdn/wpm/*.js has been added to robots.txt to prevent Google crawling the JavaScript.
