【报Bug】nvue中list组件少渲染数据

示例代码：

<!-- 普通模式演示(nvue) -->  
<template>  
    <view class="content">  
        <list :style="{ height: height, background: '#000000' }" @loadmore="queryList(pageNum+1,5)"

                @disappear="Disappear(item)" @click="itemClick(item)">

操作步骤：

分页获取数据，最好是每页几条数据（数据类型中含有视频和图片）
在列表中根据类型渲染出数据即可

预期结果：

数据正常显示

实际结果：

数据少渲染，导致页面卡中间
