Summary: Changelog: [internal] There is a possibility of race between updating scrollview's state and virtualised list asking for layout of individual cells. To make sure the race doesn't happen, state must be updated before dispatching onScroll event. Android has implemented a different mechanism to tackle this issue in D28558380 (https://github.com/facebook/react-native/commit/b161241db2ef74d2e4bff36d4972f5f0312dcc44).
