 * Stop errors in some components from breaking the whole app.

 *
 * @see https://reactjs.org/docs/error-boundaries.html
 *
 * @example
 * ```tsx
 * <ErrorBoundary><p>this might fail</p></ErrorBoundary>
 *
 * <ErrorBoundary
 *   key={someName}
 *   fallback={({error}) => {
 *     return <div>An error has occurred: {error}</div>;
 *   }}
 * >
 *   <p>a component that might fail</p>
 * </ErrorBoundary>
 *
 * <ErrorBoundary fallback={<p>a fallback</p>}><p>this might fail</p></ErrorBoundary>
 * ```
