.idea files break "npm-internal publish"

[l-r]

having a folder with .idea files prevents the publish function from working normally.

It returns:

Aborting: the package contains the following files not tracked in Git.
This is often a mistake. Use -f/--force to override this check.
  .idea/.name
  ...

If I move those files outside of my project folder everything works fine.

Seems like there an issue with non_git_files_present at
