View mode "docs" seems to be ignored

[jonhuteau]

Describe the bug

After upgrading from 6.0.0-alpha.28 to 6.0.0-alpha.29, it looks like all my default URLs of stories are wrong.

When I navigate between stories, I have http://localhost:6006/?path=/story/packages-ui-box even if in my MDX I define viewMod to docs (should be /docs/packages-ui-box).

Set addParameters({ viewMode: 'docs' }) in preview.js doesn't seem to fix this.

Expected behavior

I'd like to render docs page instead of story one by default.

Code snippets

<Meta
  title='Packages/UI/Box'
  component={AaBox}
  parameters={{ 'viewMode': 'docs', subcomponents: {'aa-box-footer': AaBoxFooter} }}
/>
