I've never run Safari and I find this interesting. So if the tab is say, torn apart and put on a second monitor (which is visible), but you're working on another tab, does it literally pause the animation halfway?
Can confirm this. It was a good feature when using youtube. I usually search for something then shift+click about 4-5 links and watch them one by one. In chrome you have to go into each on of those tabs and pause the video to avoid a clusterf*ck of different sounds. With safari it seems to do it automatically.
