BACK has been flattened?

I updated from PSE7 to PSE2020 a few days ago. I've just noticed that "back" in the Organizer no longer keeps a stack of views/selections -- instead it always goes back to "all media". For example, in PSE7 I could double-click another tag to take a quick look at something else, then click "back" (or I think it was labeled "previous view" or some such) to get back to my current work.

Am I missing something? Or is there a way to get the old, richer behavior back?
