On addon-docs DocsPage, PropType.shape renders as unknown

[ghost]

I have a component with the following proptypes:

Credits.propTypes = {
  areas: PropTypes.arrayOf(
    PropTypes.shape({
      position: PropTypes.string.isRequired,
      names: PropTypes.arrayOf(PropTypes.string).isRequired,
    }),
  ).isRequired,
};

But on the DocsPage I am getting unknown[] instead of the shape definition inside the array:

Hi! I am going through and cleaning up old issues in the repo. We just shipped a ton of improvements in Storybook 7.0, and I suspect this bug might be fixed already. Can you please try it out? If this issue persists with the latest version, please open a new bug report with a 7.x reproduction. Thank you so much! 🙏🏼
