I ran into an issue while adding page transitions with React CSSTransitionGroup.
The problem is that animation stops working as expected if I access offsetHeight of the transitioned component while it still being animated.
Check out this example on Codepen: http://codepen.io/anon/pen/pgyBvO.
Page transitions work just fine. Now uncomment console.log(this.refs.container.offsetHeight) on line 12 and try again: it skips the enter animation of the right page.
