 * If the `contentSize` is not provided, then the `contentSize` will
 * automatically be determined by the size of the `RKScrollView` subview.
 *
 * The `RCTScrollView` may have at most one single subview. This will ensure
 * that the scroll view's `contentSize` will be efficiently set to the size of
 * the single subview's frame. That frame size will be determined somewhat
 * efficiently since it will have already been computed by the off-main-thread
 * layout system.
