For anyone curious, here's a proof-of-concept of how to implement a <Modal> that manages its own transition out when it's unmounted using just ReactDOM.createPortal and React.useLayoutEffect.

awesome thanks!!

Ok it all makes sense now. I’d forgotten about useLayoutEffect. Haven’t had to write much react recently.
