If setHidden:YES has been called more than two times then setHidden:NO needs to be called more than once before the subview shows again.

2. Call setHidden:YES on one of the arranged subviews within an animation block
3. Call setHidden:YES two more times
4. Call setHidden:NO on the subview

Expected Results:
The subview is visible and isHidden returns NO

Actual Results:
The subview is still hidden and isHidden returns YES

Regression:
Tested on iPhone 6S and simulator running iOS 9.2.1
