小程序Component组件中videoContext播放失败？

每个模块用的是一个Component，相同的代码，如果我把他放在index页面上，videoContext的play事件就能自动调起，需求需要将video放在Component里，videoContext的play事件就不能自动调起播放事件如下

<view wx:for="{{list}}">
    <view>
       <video id="index{{index}}" src="{{item.video_url}}" wx:if="{{playIndex==index}}"></video>
    </view>
    <view id="{{index}}" class="cover" style="display: {{playIndex==index?'none':'block'}};" bindtap="videoPlay">
      <image class="coverImg" src="{{item.poster}}" mode="scaleToFill">
        <image class="playImg" src="https://timgsa.baidu.com/timg?image&quality=80&size=b9999_10000&sec=1524569209313&di=ed6fbf799d057b1e2b4047276d35fc76&imgtype=0&src=http%3A%2F%2Fpic.orsoon.com%2Fuploads%2Fallimg%2F1601%2F24-1601021621070-L.png" mode="scaleToFill"></image>
      </image>
    </view>
</view>

      还是有问题，这个bug是怎么回事，点击完第一个视频，在点击第二个视频，播放时正常的，但是在点击第一个视频的时候，有视频声音，说明.play()函数执行了，但是页面是黑屏，最出事video的样子，麻烦您看一下代码片段https://developers.weixin.qq.com/s/8t34wYmf7Mby
