What steps will reproduce the bug?

Create the following files to scan:

scan/
  subdir/
    a.js
    .b.js

Create the following script:

'use strict'

const fsp = require('node:fs/promises')

;(async () => {
  const globs = [
    'scan/subdir/{.,}*.js',
    'scan/*/{.,}*.js',
    'scan/**/{.,}*.js',
    'subdir/{.,}*.js',
    '*/{.,}*.js',
    '**/{.,}*.js',
  ]
  for (const glob of globs) {
    console.log('glob: ' + glob)
    if (glob.startsWith('subdir/')) process.chdir('scan')
    for await (const entry of fsp.glob(glob)) {
      console.dir(entry)
    }
  }
})()

Whenever ** is used in the pattern, the dot (hidden) files are not matched, even though the pattern specifically requests them.

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

Always reproducible as long as ** is used in the pattern and the pattern is matching dot (hidden) files.

If the pattern is * or an explicit directory name, then the dot (hidden) files are matched. So this is specific to using globstar (**).

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

The dot (hidden) files should be matched after the globstar because the pattern is specifically requesting them.

What do you see instead?

When globstar is used in the pattern, the dot (hidden) files are not matched.

Additional information

The described scenario works as expected using node-glob and bash, so the behavior of the built-in function in Node.js is inconsistent.
