URL: https://github.com/apache/incubator-weex/issues/3165
 
 
   ## Describe the bug
   在div中使用v-for指令时,如果对该div或div的字节点通过动画模块使用动画效果,会出现异常并无效。
   
   ## To Reproduce
   ```html
   <template>
     <div>
       <div :ref="'div'+i" v-for="i in [1,2,3]" style="width:30px;height:100px;background-color:blue">
         {{i}}
       </div>
     </div>
   </template>
   
   <script>
     export default {
       mounted(){
         var animation = weex.requireModule('animation');
           animation.transition(this.$refs.div1, {
             styles:{
               width: '200px'
             }
           })
       }
     }
   </script>
   ```
   
   ## Environment
   
   * Device:  xiaomi 5 sp
   * OS: Android 8.0.0
   * Version 0.28.0
   * Build from source: no
