[TIMOB-4179] iOS: KitchenSink: Base UI>Modal Windows, choosing page curl then changing orientation results in poor animation

Description: When testing Base UI>Modal Windows, I brought up partial page curl, then rotated the device. The page curl did not rotate with the view. Closing the view in the state causes the animation to lewd bad since the curl has to move then animate. Steps to reproduce: 1) Install KS 1.7.0 on iPad 1 2) Navigate to Base UI>Modal Windows 3) Choose page curl 4) Change orientation 5) Click close Result: Curl stays in place during orientation change, then on close, animates poorly Expected Result: Page curl moves with other UI elements Notes: OCCURS on 1.6.2 OCCURS on iPad 2
