in iOS 10 on iPad Air, it seems like there are different / sporadic features depending on the content when I play a video in Safari. For example:
- Sometimes video keeps playing, even when I switch to another Safari tab, as with todays NFL game on CBS.com. Other times it stops immediately I switch tabs.
- Some videos have Airplay icon, others do not
- Some videos have the minimize / picture-in-picture icon. Others do not and AFAIK there is no way to use those videos in PIP unless I'm missing something.
