Scrollbar jumps on wizard example

[jcubic]

The wizard example is broken. There is a loader at the top that keeps spinning. The scrollbar jumps because something is added at the bottom of the page. The bottom scrollbar is added and removed probably because of the animation. And there are some warnings in the console from React:

Warning: ReactDOM.hydrate is no longer supported in React 18. Use hydrateRoot instead. Until you switch to the new API, your app will behave as if it's running React 17. Learn more: https://reactjs.org/link/switch-to-createroot

Warning: Expected server HTML to contain a matching <div> in <div>.
