【报Bug】map组件在返回上一个页面报错

示例代码：

  <view>  
    <map ></map>  
  </view>  
</template>  

<script>  
  export default {  
    data() {  
      return {  

      }  
    },  
    methods: {  

    }  
  }  
</script>  

<style>  

</style>  

操作步骤：

  <view>  
    <map ></map>  
  </view>  
</template>  

<script>  
  export default {  
    data() {  
      return {  

      }  
    },  
    methods: {  

    }  
  }  
</script>  

<style>  

</style>  

打开页面之后返回上一个页面就会出现报错

预期结果：

t.setMap is not a function

实际结果：
