Thanks @bhbryant!

Is this still working for you ? It's not working for me anymore... This is what I'm seeing

• Stripe DOES in fact initialize an iframe; without Stripe on the page, no iframe is found
• However, with Stripe and within that iframe, if I search for a generic input element, it defaults to an input I had put on the page

It's as if Stripe's iframe is "deflecting" to my regular view...

I added some helpers for Stripe SCA in case anyone needs that: https://gorails.com/blog/fill-in-stripe-elements-js-for-sca-3d-secure-2-and-capybara

Was wondering if there was any update to this for Stripe's Payment Element? Have been struggling to get this to work with the new way. Oddly, I can get it to work within a pry, but not when it runs by itself.
