Summary:
When animating the frame of a UITextView the content isn't revealed in an animated way but just shrinks in one go.

Steps to Reproduce:
Run the sample project:
https://www.dropbox.com/s/umw8y7sufra17q1/TextViewTest%20Animation.zip

Tap the table view cell once to expand.
Tap the table view cell once again to collapse.

Expected Results:
The collapse animation should be symmetric to the expand animation

Actual Results:
The collapse happens non-animated in one go.

See the screen video. iOS 7.0 is first and you can see that the animation is OK in both directions. iOS 7.1 beta 5 is second with the collapse being non-animated.

Regression:
On iOS 7.0.x the collapse is animated correctly.
