请官方大佬看下 share-element 共享过渡，代码实例

// a 页面
<share-element transition-on-gesture shuttle-on-push="from" class="box" key="box">
  <root-portal>
    <view class="box" class="box" bind:tap="jump"> tap me</view>
  </root-portal>
</share-element>
// b 页面
<share-element class="img-wrp" key="bot" transition-on-gesture>
  <root-portal>
    <view class="bot" bind:tap="jumpPage" ></view>
  </root-portal>
</share-element>

求回复~
