Tried to create an account on testing ; the invisible captcha floating button thing appeared, but clicking "sign up" caused the button to become disabled for a bit, and then it became re-enabled? Didn't receive any email.

This code looks like it work! One weird edge case with aliases which I think we fixed:

Code tested and works, there are some challenges with alias accounts i.e. mek+blah@archive.org but I believe that can be handled in a separate PR which addresses #8258 (comment)
