Reported by g...@greggman.com, Aug 31 
UserAgent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/68.0.3440.106 Safari/537.36

Did this work before, YES, IIRC.  I used this feature for a rendering heavy WebGL page as it would drain my batteries so I made it auto stop on blur and auto start on focus, that way which I Cmd-Tabbed back to my text editor the rendering would stop and I'd get a much better battery life. I know that worked as I used it for months 5 years ago.

I was trying to add that feature to a new page bu now that blur/focus are not working in Chrome I can't make the feature work.
