Contrato
- createRoot is exported from react-dom/client and is absent from the react-dom root entrypoint
- flushSync around root.render commits the root DOM before flushSync returns
- createPortal places its child in a separate target while preserving context from its React ancestors
- a click from a portal child bubbles to its React ancestor despite separate DOM ancestry
- root.unmount synchronously removes both root and portal DOM
- root.render after root.unmount throws Cannot update an unmounted root
