FileSystemWatcher does not trigger onDidDelete() for file when folder is deleted

[liorfr]

I've created a FileSystemWatcher for two files in the following manner:

  const MTA_YAML = "mta.yaml";
  const DEV_MTA_EXT = "dev.mtaext";
  const fileSystemWatcher = workspace.createFileSystemWatcher(
    `**/{${MTA_YAML},${DEV_MTA_EXT}}`
  );

  fileSystemWatcher.onDidDelete(
    (uri) => {
      console.log("*********File deleted:  " + uri.fsPath);
    },
    undefined,
    disposables
  );

When I delete a folder that contains the watched files, the onDidDelete() is not triggered.

Please note

1. When the folder is deleted via the terminal with rm -rf <folder name>, the onDidDelete() does get triggered
2. When the file is open in the editor, the onDidDelete() does get triggered

Steps to Reproduce:

1. Create a folder
2. Under the new folder, add a file named "mta.yaml" (the new file is opened in the editor)
3. Close the new file so that it will not be visible in the editor
4. Click on the folder and press "delete" (approve the deletion)
