微信 version 8.0.16: scroll-view 组件, 设置了如下的代码, 快速滑动上拉的时候, onLoadMore 方法有时会不触发, 请问是什么原因导致的, 有解决方案吗?

scroll-y
style="height: calc(100vh - {{ navigationBarHeight }}px - 143rpx)"
class="scroll-wrap"
bindscrolltolower="onLoadMore"
lower-threshold="0"
refresher-enabled="{{ true }}"
bindrefresherrefresh="onRefresh"
refresher-default-style="none"
refresher-triggered="{{ isTriggered }}"
refresher-threshold="{{ 100 }}"
