AutoSwapLayout with screenshare causes the client to lock up

[capilkey]

If you join a meeting with userdata-autoSwapLayout=true and then start a YouTube video share or share your screen you will see the CPU usage for the browser spike. The YouTube video or screenshare will never show also.

I've tested with beta6 and master and both show the issue.

To test you can use https://mconf.github.io/api-mate and set the parameter in the "Custom parameters" section.

Still happening in beta-9 on master.
