You've done very good research so there's not much I can add to that.

If it is such a mission critical piece of info (or there's a manager
that's willing to make you waste time on it) you could try a difference
approach. Perhaps you can implement a "ping" feature with JavaScript.
Write some client-side code that runs at specific internals (perhaps
once a minute) an performs an HTTP request to the server. Store these
pings in the database. As soon as they stop coming in, you can assume
the user closed the browser (or had a network outage or hibernated his
computer or your script stopped working). On this line, you can capture
the onbeforeunload event (not sure about the exact name) and send a
"bye-bye" ping to the server (if you're very lucky, it may even get on
time to the server).

This method is fluky, unreliable, difficult, impossible or all of the
above so it may suit your problem :)
