The way this works is by always storing the last url the user visited, expect if that was any URL we want to ignore (AJAX, file/image, edits, sign-in pages, ...). If a user then presses sign in and signs in, they are redirected back to the last stored location. (It makes use of the fact that Rails uses session cookies also for non-signed-in users to identify them across different requests.)
Normal devise sign ins already make use of the location, thus I only had to edit the redirects for our customized sign-in endpoints (mobile sign in and 2FA).
When doing a 2FA sign in (email based), you first sign in with email and password, then it sends you back to the page you were looking at before going to the sign in, while asking you to check your mail. The link in the email will again send you to that same page when used.
