so if i have 2 videos on the page, one is playing, and now i play the 2nd one.
The 2nd one will cause the first one to exit video view, and cause this function
to get called. Should we pause the first one?

I thought we only allow one MediaPlayer instance to live per renderer process.
Do I need to take care of this case?
