I consider it as a bug in iPhone's safari.
When I want to right click a file, I try to hold the item. But in both iOS simulator (iOS10.0) and real iPhone6(iOS10.2), they don't respond to my action.
When I double click a file, iPhone think I want to zoom. Although I added no-scalable to viewport, it zoomed.
Both bugs exist in iPhone Chrome as well.
Everything works fine in my Nexus, so I think this is a bug in iPhone.
