NPM publish/pack doesn't include content from symlinked directories on Windows

Question

NPM doesn't follow directory symbolic links, nor directory junctions. Is there some configuration or way to force NPM to include also files from such directories?

Minimal reproducible example. Folder structure:

hello/
├── foo/
│   └── foo.js
└── bar/
    ├── package.json
    ├── bar.js
    └── foo/ (SYMLINK)

Two types of symlinks doesn't work:

bar> mklink /J foo ..\foo

bar> mklink /D foo ..\foo

The pack command

bar> npm pack

produces the tar package without foo/foo.js and no foo/ folder.

$ npm -v
