What steps will reproduce the bug?

fsPromises.glob has inconsistent parentPath behavior when passed withFileTypes option.

According to the documentation, dirent.parentPath should return path to the parent directory, but in some cases it doesn't.

How often does it reproduce? Is there a required condition?

This occurs when a path is passed that does not contain a wildcard(*) in the filename portion.
For example, passing ./path/*/file.txt will result in different behavior than passing ./path/to/*.txt.

import { glob } from "fs/promises";
import path from "path";

// If the file name is a wildcard: OK
for await (const dirent of glob("./path/to/*.txt", { withFileTypes: true })) {
  console.log(dirent.parentPath);
  //=> /Users/me/work/test/path/to

  console.log(path.join(dirent.parentPath, dirent.name));
  //=> /Users/me/work/test/path/to/file.txt ✅
}

// If the file name is not a wildcard: 💣
for await (const dirent of glob("./path/*/file.txt", { withFileTypes: true })) {
  console.log(dirent.parentPath);
  //=> /Users/me/work/test/path/to/file.txt

  console.log(path.join(dirent.parentPath, dirent.name));
  //=> /Users/me/work/test/path/to/file.txt/file.txt 💣
}

What is the expected behavior? Why is that the expected behavior?

parentPath contains the path to a file, not the path to a directory.

What do you see instead?

The path to the file, not the path to the directory

Additional information

As far as I can see, something similar is happening with fs.globSync.

I'm looking into this. A notable difference is that the incorrect dirent is created from DirentFromStats, while the correct dirent is created from Dirent.
