SL2 Right-Click Trigger Fails

Hello. While this issue has been reported over two years ago, I have not been able to find a fix or workaround for this problem. The right-click trigger is broken in some cases. For example, if you use a right-click trigger to show a layer on a slide, it fails for me consistently. I have uploaded a test file to Tempshare here:

Slide two is setup to show a layer on right clicking the circle. Please help test this and post your results. I believe this to be a bug and want it finally addressed. PS. Right-click functionality also fails to work in some browsers when run locally. It was reported that running on an LMS or webserver will enable right-click functionality to work, however, it still fails for me. Given that this issue is over two years old now, I would really like this addressed and a permanent solution achieved.
