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。
