Bug: `setState` function changes on every re-render

[Rajas Paranjpe]

In the normal React.useState(), the setState function never changes. This is great when used in a React.useEffect() dependency array, because then it is not called every time the setState function changes.

However, useBatchedState behaves differently than expected. The setter function changes on every re-render, which can mess up calls to React.useEffect.
