         (project-files-relative-names nil) ; override global to ensure
directory components are retained
         (dirs-to-watch
          (delete-dups (mapcar #'file-name-directory
                               (project-files
                                (eglot--project server))))))

"project.el has a global, project-files-relative-names, which influences
project-files to return results without parent directory prefixes and this
causes file-name-directory to fail to detect directories at the root of the
parent. We disable project-files-relative-names to ensure complete results."
