Just tested on try.
In the quotes the username is anonymized but not the avatar (see Do you use a mobile device for ALL your work? Tell me how! - #6 - tech - Discourse Demo).
As an administrator instead, every time I tested this function making an anonymous user, when I click the back button of the browser twice to return from the user’s admin page to the topic I was reading I always end up on page 404.
That’s true, because Discourse try go back to the original admin user page, which is no longer available, then reload the admin user page of the anonymous user, the second click on the back button would like to return to the original-user/summary page that no longer exists and you go to page 404 instead.
