storybook: Storybook 5.2 static app docs either has missing props section or props descriptions

Describe the bug After updating to Storybook 5.2, the props section is rendering fine when running via storybook locally but after generating a static app with the storybook build, the props section either does not show up or the descriptions are missing.

To Reproduce Steps to reproduce the behavior:

1. Create a component with proptypes
2. Add stories for it.
3. When viewing it locally it works fine
4. After running yarn build-storybook and viewing the static app, the props section has the above issues

Expected behavior The props section should be the same as it is when running storybook
