It's a software issue, been like that for as far as I remember. I believe it might be a bug in the software itself
If you want my boring technical guess at the problem, I think it stores session data inside a database to store last seen timestamps, and the cookie life isn't too high, and using more than one tab confuses the software because back when it was written tabs weren't very common.
See, I told you it was boring
There isn't much of a fix except don't log out, only visit in the one tab/window, and only use one computer to log in. Doing the opposite to any of these generally clear your recent visited posts.
For some reason Safari for iPhone behaves weirdly where Safari for iPad doesn't
And posts will generally be marked as read after a few minutes from you navigating away from the site/not going from page to page
