 * Reaction will be automatically disposed when the component is unmounted.
 * If this reaction creates other reactions, those reactions will NOT be disposed.
 * In that case create a reaction manually inside a `useEffect` hook as described in
 * {@link https://mobx-react.js.org/recipes-effects | mobx-react documentation }.
