React-styleguidist: PropTypes.oneOf in combination with a description results in render warnings.

[ZwaarContrast]

When adding comment above a propType defined with the oneOf type, that results in render warnings.

Warning.
Warning: Each child in an array or iterator should have a unique "key" prop. Check the render method of 'Group'. It was passed a child from PropsRenderer. See https://fb.me/react-warning-keys for more information.

Check out the forked example here:
https://github.com/ZwaarContrast/example

Heading.propTypes = { /** * This will result in a render warning */ size: PropTypes.oneOf( ['small', 'medium', 'large'] ), }

This is an issue with react-group. I have created a pr with react-group. https://github.com/sapegin/react-group/pull/1

Thanks @roychoo! The PR's been merged into react-group.

To anyone having this issue on RSG 4.6.3: update dependencies of RSG (or simply delete and reinstall it) to pick up the new version of react-group to have this issue resolved.
