<swiper style="width: 100%; height: 300px;" autoplay="{{ true }}" skip-hidden-item-layout="{{ true }}" indicator-dots="{{ true }}">
  <block wx:for="{{ testImgs }}" wx:key="index">
    <swiper-item>
      <image src="{{item}}" mode="widthFix" />
    </swiper-item>
  </block>
</swiper>

条件：随便五张图片，开启自动播放，图片image设置mode为widthFix

问题：自动播放到第五张回到第一张时，第一张图片不展示，第二张恢复正常
