live-player中同层渲染的cover-view和cover-image内容，在调用全屏API,再推出全屏后，cover-view和cover-image不显示

用view代替cover-view的方案已经尝试，媒体流未加载时候显示，加载出来以后直接不显示，但是点击相应位置还是可以触发事件

<live-player id="livePlayer" object-fit="fillCrop" :src="liveDetail.playUrl.flv" mode="live" autoplay @statechange="statechange" @error="error" style="width: 100%; height: 225px;">
 <cover-view class="definition-selector" @click="switchDefinition">标清</cover-view>
 <cover-view class="loading-wrap" v-show="!inPlay">
  <cover-image class="loading" src="/static/live/loading.png"></cover-image>
 </cover-view>
 <cover-image class="player-control-btn" v-show="!playerIsFullScreen" @click="livePlayerFullScreen" src="/static/live/fullScreen.png"></cover-image>
 <cover-image class="player-control-btn" v-show="playerIsFullScreen" @click="exitFullScreen" src="/static/live/exitFullScreen.png"></cover-image>
</live-player>
