[Ninja'd] I am not too much familiar with the terminology here, but I humbly think that not having focus does not necessarily mean a window is not visible. I often have more than one visible window; maybe one where I am currently working, and another one at the side with a football game streamed or whatever. I wouldn't like the football stream to be stopped when this window looses focus. But when the stream gets totally hidden, be it that I open a new tab in the same window, or place some other window in front of it, the streaming application might want to save bandwidth by pausing the streaming of the visuals, while streaming on the audio. Thus, I'd consider an api for detecting the visibility state of every HTML element useful (totally visible, partially visible, hidden - or a percentage value).
