@evanSe Docs in #10831 does not compile because of this overlooked issue. Let's merge in please 🙏

Thx for merging @evanSe. This PR lead me to one more thought - the issue here was that the custom editor component was used outside of the editor prop (it was both a renderer and an editor in this case). It was failing on property access on undefined context at useHotEditor. Shall we maybe check it gracefully and issue a warning if someone places custom editor outside of editor prop?
