"StyledComponent" Component - No propTypes defined!

After upgrading from Storybook 4.x.x to 5.0.6., I am not able anymore to see the assigned propTypes for Styled Components in Storybook anymore.

That’s what I see in Storybook:

That’s what I have coded:

const TabBar = styled.div`
  display: flex;
  flex-direction: column;
`;

TabBar.displayName = 'TabBar';

TabBar.propTypes = {
  children: PropTypes.arrayOf(
    PropTypes.shape({
      type: PropTypes.oneOf([TabBar.ContentTab]),
    }),
  ).isRequired,
};

And I would expect to see the children prop types instead.

Note: It works for other components which haven’t defined with styled components though.

@oknoorap Nope, will comment here when it is. If anybody else wants to take a crack at it, they’re more than welcome!

@shilman This may also be related to the bug I logged for the missing prop table in TypeScript: https://github.com/storybooks/storybook/issues/6345
