This is interesting - on mac, on both 31 and 32, I am able to close the tab by clicking the [x] or using cmd-w (ctrl-w on Windows). I've also tried uncommenting the startTimer calls in the html file, but I still don't see the same problem as you do. Can you perhaps provide a screencast, and check in a clean profile?
