Converted from a codepen.io test case:

// iOS misreports scroll position! Set it, check it immediately and it's correct but then 
// on the next requestAnimationFrame (or sometimes in the same one), it REVERTS to the previous scroll position!!!

You must run this on iOS Safari in the /debug/ window of CodePen so that it's not in an iframe https://codepen.io/GreenSock/debug/16c435b12ef09c38125204818e7b45fc?editors=0010
