bug: fa-perspective not being applied to animation in Chrome

[rohanrehman]

<fa-app ng-controller="famousCtrl" style="width: auto; height: 800px" fa-perspective="1000">

   $scope.box.rotate.set(-45 * Math.PI/180, {duration: 1200, curve: Easing.inOutExpo});

and an fa-modifier

  fa-rotate-y="box.rotate.get()"

the box will rotate with no perspective applied until chrome (Version 41.0.2272.118 (64-bit)) is resized, resizing chrome before the animation is called makes no difference.

Bug is not reproduced in Safari.
