BTW, my previous reply was good until tonight.

New support for anonymous access has been enforced and, in that particular scenario, instead of forwarding to a login page, the upper right "Logged as" will be dynamically changed to "Logged as anonymous". So, basically, in that scenario, when a login is done on another browser or device, which makes the current session obsolete, you can simply click on Login, which is now a toggle between Login/Logout, from the upper right, and simply do the login from that route.
