Stripe Checkout is a popular payment solution that overlays CC forms on top of your website. What happens in my online shop is that customers who use 1Password cannot checkout, as 1Password messes with the cart form.
Here is a quick simplified demonstration of the problem.
How can I prevent 1Password from filling out my input fields?
1Password Version: 6.3.1
Extension Version: 4.5.6
OS Version: OS X 10.11.5
