vant的PullRefresh-下拉刷新下拉过程中不断报错的解决办法

vant 的 PullRefresh 下拉刷新下拉过程中不断报错，错误提示如下：
[Intervention] Ignored attempt to cancel a touchmove event with cancelable=false, for example because scrolling is in progress and cannot be interrupted.
如我的代码结构
`<van-pull-refresh v-model=”isLoading” @refresh=”onRefresh”>

<ul class="flex">
    <li v-for="(item,index) in piclist" :key="index" @click="check(item,index)">
        <img :src="item.img+'?w=264&h=300'"alt="">
        <span class="iconfont icon-xuanzhong" v-if="selectedIndex===index"></span>
    </li>
</ul>

</van-pull-refresh>`
给 PullRefresh 包裹的 ul 标签加一个样式
ul{touch-action: none;}
就能解决报错的问题了。
