Failed top-level autologin on mobile redirects to desktop.
In a private browser window, visit the mobile site login page: https://en.m.wikipedia.org/wiki/Special:UserLogin – you will be redirected to https://en.wikipedia.org/wiki/Special:UserLogin?centralAuthAutologinTried=1¢ralAuthError=Not+centrally+logged+in, which is the desktop site.
I ran into this by chance today while testing a CentralAuth/MobileFrontend config change.

That's weird, we stash the exact starting URL to the token store and use that for returning, there shouldn't be any domain negotiation involved.
Except apparently WebRequest::getFullRequestUrl() returns the desktop domain regardless of what is in the actual request. Ugh.
