This is an example of how to render React component for Highcharts tooltip using React portals. See Chart.tsx
and Tooltip.tsx
files below. Latest Highcharts version is required for the example to work correctly (9.0.0 at the time of writting).

Actually, you're right. It's on the first render, I didn't notice it at first. I guess I do need the
setTimeout
then. Thanks 🙏
