[TIMOB-4661] iOS: Rotating iPad while scrolling a scrollable view in popover results in smaller popover

Description: While testing KitchenSink iPad in landscape mode, on the Main Tests>Popovers>Popover 3 test, I scrolled the view from View 1 to View 2. As I scrolled, I rotated to portrait. The result was the popover window was 25%-30% smaller. This test is most likely an edge case as you must hold the view half-scrolled while rotating for it to occur reliably. Note: Does not occur with the same steps but from portrait to landscape. See attached screenshot. Steps to reproduce: 1) Launch KS iPad built with 1.7.2 2) Navigate to Main Tests>Popovers>Popover 3 3) Ensure device is in landscape mode 4) With the scrollable view up, scroll the view so half of view 1 and half of view 2 is visible. 5) Rotate to portrait while continuing to hold the view half-scrolled Result: The scrollable view size is reduced, see screenshot Expected: Scrollable view size remains the same
