When using Mixpanel's track_links method in a React app, we need to wrap the method in a useEffect hook and a setTimeout to prevent errors like "this.config is not defined" or "cannot access property 'img' of undefined".
You can reproduce this by running pnpm dev and clicking on the link that says "Go to page demonstrating how it breaks without a setTimeout".
The index page does not break as it uses a setTimeout to wrap the track_links method, but the other page does break.
This does not work when using refs either, as shown in the using-refs.tsx page.
Created to add a reproduction for issue mixpanel/mixpanel-js#419 (comment)
