Storybook Docs 6.1.1 not able to set components to MDXProvider as global scope

Describe the bug After upgrading from 6.0.25 Storybook Docs no longer recognizes components passed to MDXProvider as global scope. It was working with the following in preview.js:

export const parameters = {
  docs: {
    inlineStories: true,
    theme: theme,
    components: {
      SomeComponent: SomeComponent,
    },
  },
};

Has the way to configure this changed in 6.1?

To Reproduce Steps to reproduce the behavior:

1. Update preview.js with a similar config to set SomeComponent with global scope
2. In component mdx docs use SomeComponent
3. Notice warning Component SomeComponent was not imported, exported, or provided by MDXProvider as global scope

Expected behavior SomeComponent is available to use in mdx docs on a global level.

@shilman I do not as it is a private project. I did update to 6.2.0-beta.1 and things are working as expected again 😄
