Only last component is shown, storyMissing is thrown for the rest

[siffash]

Describe the bug
Storybook loads all components one by one (not all of them at once) and shows only the last one.

To Reproduce
Steps to reproduce the behavior:

1. Create components and stories for them.
2. Load them into Storybook, everything works fine.
3. Export the components with their stories files to bit.dev
4. Install the components from bit.dev to another project.
5. Load them into Storybook (see the code snippet).
6. The components are loaded one by one, and only the last component is shown.
7. In the console (when verbose is checked):
   7.1. setStories is run for each component (not once for all components)
   7.2. storyMissing is thrown for all components except the last one:
   (18) message arrived at manager storyMissing undefined

Expected behavior
All components to be loaded and shown together.

Code snippets
config.ts:

import { configure } from '@storybook/react';
const req = require.context('@bit/', true, /stories\.tsx$/);
function loadStories() {
req.keys().forEach(req);
}
configure(loadStories, module);

The problem was with node_modules of each component, removing that directory for each component solved the issue.
