Props table shadow missing in Safari

[apust]

Describe the bug
Props table rendered from <Props /> does not have a shadow in Safari. It has a shadow in Chrome.

To Reproduce

1. Create a storybook with addon-docs.
2. Create a sample component with props.
3. Add <Props of={SampleComponent} /> to your MDX docs file.
4. Open page with props in Chrome and Safari. Compare them visually.

Expected behavior
Props table should look the same in all modern browsers.
