Animation issue in iOS 7.0.3

[lane128]

Hi, I used your JazzHands to build a app guide page. and found a little issue about position of animation issue in iOS 7.0.3 while in other version of iOS is fine. I made a demo about how that issue appears. here is the repo : https://github.com/lane128/WLJazzHandsDemo

here is the incorrect position after animation. (iOS 7.0.3) here is the correct position after animation (iOS > 7.0.3)

Hope you can help me to solve it. Thanks.
