/**
* 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.
