Right-click on Matrix visuals unresponsive

v-yuta-msft ,

I had not noticed the issue until seveal of our users complained.  I then tried it in the Service and did not see the issue - until I closed and re-opend my browser session, then I was able to recreate it.  My previous browser session had retained the expected behavior since, I presume, it was refreshed/opened prior to the issue appearing.  Thus it worked as expected in the "old" session but once I refreshed it no longer worked.

So, I guess if one has an older browser session open and the right-click still works, don't close the session.  😛
