 *
 * UISplitViewController resizes column views natively - on display mode change or column resize, so
 * these updates should be passed to React to allow syncing the ShadowTree layout of SplitViewScreen
 * subtree. This controller observes its own view's frame via KVO and notifies `viewFrameOriginChangeDelegate`
 * whenever the frame origin changes.
