Pause video when "Pause playback when video is no longer in view"

[clara-am]

I'm trying to use these option in the config, however it doesn't work like I was expecting.
I would like to pause the video when you minimize/left to see the window and not only when you navigate to other place and the component lefts to be visible. Maybe using sth like these in:

document.addEventListener( 'visibilitychange' , function() {
if (document.hidden) {
self.onWidgetInview();
} else {
self.onOverlayClick();
}
}, false );
