May have had something to do with session handling in the admin.
Prior to those versions of zen there was an admin\includes\classes\sessions.php that was removed in zen v138 and newer.
This file may have had an influence on it.
Welcome!

The thing I saw was when I was looking at the user tracking log, someone/something added a large number of items, when I refreshed the logs every entry showed the same thing in the cart rather than just the entry that had something in their cart, but I think it was identical to what was shown on the who's online screen.

So, I'm not sure if that is the same that you observed years ago, but it did appear as the who's online shows (a single "window" with all cart information shown including which session had the item(s).)
