easyUI for vue，tabs调用tabClose事件时，获取到打印的panels是正确的，但是显示的TabPanel数量不正确。

<template>

  <div class="main-box">

    <SideMenu class="aside-nav"

              :data="menus"

              :collapsed="collapsed"

              @itemClick="addTopMenus($event)">

    </SideMenu>

   

    <Tabs ref="tabs"

          :scrollable="true"

          @tabClose ="onTabClose($event)"

          style="width:800px;height:400px">

      <TabPanel v-for="(item, index) in panels"

                :key="index"

                :title="item.text"

                :closable="true">

        <div style="padding:20px">{{currentIndex}}</div>

      </TabPanel>

      

    </Tabs>

  </div>

</template>



<script>

import sideMenu from './components/menus.json'



export default {

  data () {

    return {

      collapsed: false,

      selectedMenu: null,

      menus: sideMenu.data.permission,



      closePanel: null,

      panels: [],

      topMenuItem: null,

      currentIndex: 0

    }

  },

  methods: {

    addTopMenus (menu) {

      let topMenus = this.panels

      

      topMenus.push(menu)

      this.currentIndex++



      // 触发点击tab事件

      this.$nextTick(() => {

        this.$refs.tabs.select(this.panels.length - 1)

      })

    },



    onTabClose (panel) {

      this.panels = this.panels.filter(p => p.text !== panel.title)

    }

  }

}

</script>
