withPageAuth redirectTo, how to go back to previous page after login?
After authentication in the /login page, I can't figure out how to route back to the previous page. I don't want to have to manually add a "referrer" query parameter in the redirectTo field, and I also want the ability to include any possible query params or anchors that existed in the previous page's URL. I can't use router.back() because apparently the redirection to the login page uses router.replace(), which doesn't write to browser history. Kinda stumped on this one!
