Describe the bug

A clear and concise description of what the bug is.

Versions (please complete the following information):

• Chokidar version: 4.0.3
• Node version: v16.20
• OS version: Windows 10

To Reproduce:

my code like this:

import { setTimeout } from 'node:timers/promises';
import { FSWatcher } from './index.js';
import * as fs from 'fs';
import * as sp from 'node:path';
const util = require('node:util');
import { writeFileSync } from "fs";

const myWatcher = new FSWatcher({
alwaysStat: true,
awaitWriteFinish: {
stabilityThreshold: 1000,
pollInterval: 1000,
},
ignored: /(..part$)|(..lnk$)|(.*.tmp$)/,
followSymlinks: false,
atomic: 2000,
ignoreInitial: true,
});

let event_array: any[] = []
let root_watch_dir: string = 'E:\my_chokidar\test'
myWatcher.add(root_watch_dir)
myWatcher.on('all', (eventName, path, stat) => {

var file_path = path
var event_name = eventName.toLowerCase()
if (stat) {
var json: Record<string, any> = { "name": file_path, "action": event_name, 'event_time': stat.mtimeMs * 1000 }
event_array.push(json)
} else {
var json: Record<string, any> = { "name": file_path, "action": event_name, 'event_time': 0 }
event_array.push(json)
}
});

I record the event watch by chokidar and store them into event_array. Then i write 1000*4M file in backgroup thread and unlink them after thread exit. What event i expect to catch is 'add' 'change' and 'unlink', but i got some 'unlinkdir' which acually not a dir at all

my backgroup thread code like this:

def create_new_file_in_dir(dir, num, init_file_content = False, init_file_size = 0):

start_time = get_current_time_in_us()

result = []
verify_dir_info(dir)
for i in range(0, num):
    new_file_name = '%s_%s' % (NEW_FILE_NAME, i)
    new_file_path = os.path.join(dir, new_file_name)
    file_dict = {}
    file_fd = open(new_file_path, 'x')
    if init_file_content:
        content = init_file_size * 'a'
        file_fd.write(content)
    file_fd.close()
    event_object = gen_event_object(new_file_path, 'add')
    result.append(event_object)

    try_to_sleep(i)

end_time = get_current_time_in_us()

print('create %d files cost:%d(us)' % (num, end_time - start_time))
return result

It didn't call mkdir at all
