Not working in Chrome for Optin Form

When I run a divi ‘optin form’ within this popup modal, it works perfectly in firefox + safar, it doesnt work at all in Chrome. The form shows up, but when you click on ‘register’ nothing happens in Chrome.

I’ve created a dummy page to show the bug in question:
