iOS9 returns double the value for window.innerWidth & window.innerHeight
The versions that are concerned are: 9.0.0, 9.0.1, 9.0.2
A few people got mad on twitter:
window.innerWidth in iOS 9 Safari returns double the number it did in iOS 8? Is this real life? tell me no — @rachsmithtweets
iOS9 Safari has the most insane bug where window.innerWidth / innerHeight is *sometimes* twice as large as it should be. ughhhh. !? — @mattdesl
iOS9 innerWidth/innerHeight is having a lot of fun these days — @ayamflow
