When watching multiple patterns (e.g. ["**/*.ts", "**/*.tsx"]), some files from linked dirs are skipped

[cristian-spiescu]

Describe the bug

I have the following dir structure:

link // a linked dir
  file.ts
  file.tsx
non-link
  file.ts
  file.tsx

Watching "." works. I.e it finds all the 4 files above. But watching [ "**/*.ts*", "**/t.tsx"] doesn't find link/file.tsx. I.e. it finds only 3 files.

NOTE: The above input for chokidar is generated by mocha.

Versions (please complete the following information):

• Chokidar version: 3.3.0
• Node version: 12.14.1
• OS version: Windows 10

To Reproduce:

Using the 2 dirs and 4 files cf. above:

const chokidar = require("chokidar");
const watcher = chokidar.watch([ '**/*.ts', '**/*.tsx'])
watcher.on("ready", () => {
    console.log(watcher.getWatched())
})

outputs:

{
  'E:\\data\\git-repos\\leave-management\\leave-management-react\\node_modules\\mocha\\node_modules\\chokidar\\lib': [ 'link', 'non-link' ],
  'E:\\data\\git-repos\\leave-management\\leave-management-react\\node_modules\\mocha\\node_modules\\chokidar\\lib\\**\\*.ts': [],
  'E:\\data\\git-repos\\leave-management\\leave-management-react\\node_modules\\mocha\\node_modules\\chokidar\\lib\\**\\*.tsx': [],
  'E:\\data\\git-repos\\leave-management\\leave-management-react\\node_modules\\mocha\\node_modules\\chokidar\\lib\\non-link': [ 'file.ts', 'file.tsx' ],
  'E:\\data\\git-repos\\leave-management\\leave-management-react\\node_modules\\mocha\\node_modules\\chokidar\\lib\\link': [ 'file.ts' ]
}

We can see that link/file.tsx is missing. So we have 3 of 4 files present.

If using: const watcher = chokidar.watch("."), all 4 files are present:

{
  'E:\\data\\git-repos\\leave-management\\leave-management-react\\node_modules\\mocha\\node_modules\\chokidar\\lib': [
    'constants.js',
    'fsevents-handler.js',
    'link',
    'nodefs-handler.js',
    'non-link',
    'test.js'
  ],
  'E:\\data\\git-repos\\leave-management\\leave-management-react\\node_modules\\mocha\\node_modules\\chokidar\\lib\\non-link': [ 'file.ts', 'file.tsx' ],
  'E:\\data\\git-repos\\leave-management\\leave-management-react\\node_modules\\mocha\\node_modules\\chokidar\\lib\\link': [ 'file.ts', 'file.tsx' ]
}
