The mobile version looks good, but the icon in the "next" button seems too far to the left?

And for the desktop version, introducing a big dedicated space for the button looks a bit off. The overlap is fine, we just need to have nicer placing.
On tech-preview it looks like this, floating in the bottom right of the modal, which is actually great, and it scrolls so all fine. (Only weird thing is the logo is missing)

Seems like my commit broke the button. Fixed it now.
