FileSystemWatcher fires 2 onCreate and 2 onDelete events

[rioj7]

Does this issue occur when all extensions are disabled?: Yes/No

• VS Code Version: 1.111.0
• OS Version: Windows 11

Steps to Reproduce:

1. Create a VSCode extension with the following JavaScript code:

   function activate(context) {
     let seqnum = 1;
     const path = vscode.workspace.workspaceFolders[0].uri.fsPath;
     const toWatch = new vscode.RelativePattern(vscode.Uri.file(path), '.vscode/foobar.txt');
     const watcher = vscode.workspace.createFileSystemWatcher(toWatch, false, true, false);
     context.subscriptions.push(watcher.onDidCreate(uri => { console.log(seqnum, 'onCreate', uri.fsPath); seqnum += 1; }));
     context.subscriptions.push(watcher.onDidDelete(uri => { console.log(seqnum, 'onDelete', uri.fsPath); seqnum += 1; }));
   }
   function deactivate() {
   }
   
   module.exports = {
     activate,
     deactivate
   }

2. Launch this extension in debug mode
3. Make sure a Workspace Folder is opened on Launch
4. With the OS File manager or from terminal create the file <workspace>/.vscode/foobar.txt
5. With the OS File manager or from terminal delete the file <workspace>/.vscode/foobar.txt
6. Look in de Debug Console of the VSCode that launched the extension.

   1 onCreate <workspace>\.vscode\foobar.txt
   2 onCreate <workspace>\.vscode\foobar.txt
   3 onDelete <workspace>\.vscode\foobar.txt
   4 onDelete <workspace>\.vscode\foobar.txt
   

7. The onCreate and onDelete events are received twice.
