fs.readdir recursive: is `parentPath` supposed to be the same as `path`?

Description of the problem

I'm curious what the purpose of parentPath is on Dirent objects when using fs.readdir or fs.readdirSync when both withFileTypes and recursive are set to true.

The reason for this issue is that I haven't found a situation where parentPath differs from path, it's always the same value. My hunch is that it's not supposed to be and there is probably a bug.

FWIW, I think it would be more useful to include the relative path versus parentPath, since parentPath is just the path.dirname(path) of each path, isn't it? If not, perhaps parentPath isn't the best name? Maybe it should be base or root or something?
