Special:NewMessages has me logged in, as who/what exactly?
This might've been filed before, though I couldn't find it.
For several months now there's on Special page I often visit from url completion history, and that's Special:NewMessages on mediawiki.org. And if I'm not logged-in, I'll simply login and return to that page.
Now the thing is however that sometimes I'm logged out (I know I am from logging at the header and the absence of certain scripts) yet Special:NewMessages appears to show something it shouldn't.
Not sure what this is or where it came from. Could be an API request cached by my browsers, could be some state being kept somewhere else I don't know, could be someone elses messages, no idea.
See screenshot for details, as well as tracking POST requests to api.php and a cookie dump.
