defaultValue={<p>hello</p>}
/>

I managed to implement support for defaultValue, but there is still a bug whereby after the first keypress in the editor, the component seems to un-mount and re-mount again, resetting the content to empty.

Due to my lack of in-depth understanding of React, I'm finding this hard to solve. For some reason, the useEffect clean-up is being called after the first key press.

@AleksanderBondar maybe you have time to take a look?
