     * Hook for adding an event listener on mount and removing it on

     * event handling (ie. via `onclick`, `onfocus` etc attributes). This
     * hook is for those rarer cases where you need to attach a listener
     * outside of your component's DOM (eg. attaching a "scroll" or "resize"
     * listener to the `window`).
