Duplicated entries when using StoryStoreV7 and auto title globs

[yannbf]

Describe the bug

When using the new stories format in main.js, given you have a folder structure like this:

With the following use case:

• As a user, I want to have auto title stories for everything but the stories under /stories/molecules.

Defining a finer grained path + wider path, like so:

module.exports = {
  stories: [
     // default title prefix
    {
      directory: '../stories',
    },
    // defined title prefix
    {
      titlePrefix: 'Composed atoms',
      directory: '../stories/molecules',
    },
  ],
  features: {
    storyStoreV7: true,
  }
}

will resolve into duplicated stories:

This appears to be "fixed" on both next and future/base (see the react-ts example).

Though I'm not sure:

1. what fixed it
2. why it was a bug in the first place
