Ad breaks don't progress when the tab isn't open
Hehehe, this is the most spiteful implementation of ads I've ever seen. You're still getting an ad view, but if I want to flip to another tab while it's playing it pauses the countdown. Surely this isn't working as intended because I fear the evil little brain that would've thought up something like this.
videos are stopping before or after an ad if the video isn't in the current browser during an ad, not continuing the video until the tab or window becomes the current one again.
