room-join
room-leave
room-topic
以上三个event，无法成功触发

代码如下：

import {
  Wechaty
  , log
} from '../'

const bot = Wechaty.instance({ profile: 'TestFun' })

bot
.on('login'   , user => log.info('Bot', `${user.name()} logined`))
.on('logout'  , user => log.info('Bot', `${user.name()} logouted`))
.on('error'   , e => log.info('Bot', 'error: %s', e))
.on('scan', (url, code) => {
  if (!/201|200/.test(String(code))){
    let loginUrl = url.replace(/\/qrcode\//, '/l/')
    require('qrcode-terminal').generate(loginUrl)
  }
  console.log(`${url}\n[${code}] Scan QR Code in above url to login: `)
})

.on('room-join', (room, invitee, inviter) => {
  console.log("room-join@@@@@@@@@@@@@")
})

.on('room-leave', (room, leaver) => {
  console.log("room-leave！！！！！！！！")
})

.on('room-topic', (room, topic, oldTopic, changer) => {
  try {
    console.log('room-topic##############')
  } catch (e) {
    log.error('Bot', 'room-topic event exception: %s', e.stack)
  }
})

.on('message', m => {
  m.ready()
  .then(msg => {

  const room    = msg.room()
  const sender  = msg.from()

  console.log((room ? '[' + room.topic() + ']' : '')
              + '<' + sender.name() + '>'
              + ':' + msg.toStringDigest()
  )

  })
  .catch(e => log.error('Bot', 'ready: %s' , e))
})

bot.init()
.catch(e => {
  log.error('Bot', 'init() fail: %s', e)
  bot.quit()
  process.exit(-1)
})

当群中拉入成员、删除成员、修改群名，理应打印出：

room-join@@@@@@@@@@@@@
room-leave！！！！！！！！
room-topic##############

实际上并没有打印出以上内容，仅仅作为消息形式，日志输出如下：（加入好友的情况）

为什么会没有触发到
.on('room-join', (room, invitee, inviter)
.on('room-leave', (room, leaver)
.on('room-topic', (room, topic, oldTopic, changer)
里面的内容呢？

谢谢！
