- 当前 Bug 的表现（可附上截图） 微信更新到7.0，video组件上面的 cover-image 组件的图片显示不出来 - 预期表现 - 复现路径 - 提供一个最简复现 Demo <video id="myvideo" class="audio_player" src="{{courseDetail.playUrl.mp4}}" autoplay="true" bindplay="didPlay" bindpause="didPause" bindtimeupdate="updatedTime" binderror="playError" bindended="playEnded" bindfullscreenchange="fullScreenDidChange" > <cover-view class="audio_player_container"> <cover-image class="audio_player_poster" src="{{poster}}"       /> <!-- 控制条 --> <cover-view wx:if="{{isFullScreen}}" class="control_bar">     <!-- 开始时间 --> <cover-view class="control_bar_time">{{playTime.currentTime}}/{{playTime.duration}}</cover-view>     <!-- 全屏按钮 --> <cover-view class="control_bar_button" bindtap="didTapFullScreen"> <cover-image src="../image/audio_player_fullscreen.png" class="control_bar_full_size"           /> </cover-view> </cover-view> </cover-view> </video>

[图片] 想用<cover-image>放一个自定义的播放按钮在这里，但是原本的没办法隐藏，用了controls和下面这个新增加的属性也都没起作用？ [图片]
