## bug说明

下拉刷新效果没有，滚动时会报 Cannot read properties of undefined (reading 'scrollTop') 
如果把   height='calc(100vh - 50px)' 改成 height="100%" (.home-main 的高度也是 100%） , 不会报错（Cannot read properties of undefined (reading 'scrollTop') ）但 loadMore 失效，只能加载第一页或者更确切的是加载 2倍的 showCount 个，能触发loadMore但视图不更新

showCount={3}， 6行元素是否一定能占满整个容器
