skyline 模式下 scroll-view + grid-view 无法实现下拉刷新，scroll-view[type="list"] 下拉刷新是正常，只要添加了 grid-view 就不支持下拉刷新了

代码片段：https://developers.weixin.qq.com/s/VZJXTbmh7tF0

示例代码：

<scroll-view type="custom" scroll-y style="width: 100%; flex: 1;" refresher-enabled="{{true}}" refresher-triggered="{{triggered}}" bindrefresherrefresh="onRefresh">
  <grid-view type="aligned" cross-axis-count="2">
    <view wx:for="{{arr}}" style="display: flex;">

    </view>
  </grid-view>
</scroll-view>
