💻 Code

My repository is intended to reproduce a bug that manifests when the following three settings are combined:

1. "rootDir": "." in the tsconfig.json file, which is required only for VS Code and eslint.config.mjs;
2. paths in the tsconfig.json file creates an alias for the path #lib/*, pointing to ./src/*;
3. imports in the package.json file creates an alias for the path #lib/*, pointing to ./dist/*.

In such cases, TypeScript suggestions merge content from both the ./dist/* and ./src/* directories:

🙁 Actual behavior

As you can see, file1.js, file2.js, and index.js appear at the same level as the src and test folders, which is incorrect.

🙂 Expected behavior

1. The setting described in point 2 should take higher precedence for TypeScript over the setting in point 3.
2. In any case, the settings in points 2 and 3 should not be merged.

Additional information about the issue

If in point 1 the setting is changed to "rootDir": "src", the bug disappears. However, in this case, you cannot use "include": ["test"] in the tsconfig.json file, which is very inconvenient. Instead, it is more practical to use the "rootDir": "src" setting in the tsconfig.build.json file.
