LGTM, if you fix the docstring I suggested.

The only other thing I noticed is that the inherited onClick prop disappeared from the props documentation. See https://paragon-openedx.netlify.app/components/statefulbutton/#props-api . It might be good to declare it explicitly so it shows up in the docs.

	/** Each state has a `disabledState` */
	/** States listed in `disabledStates` will not be clickable */
