在实机上看不到cover-view/image组件 - WXOPEN Club

当前 Bug 的表现

map组件中用了cover-view呈现按钮，但是在手机上（手机系统安卓8.0.0，微信6.7.3）看不到按钮

（手机端开发版界面截图）

预期表现（开发者工具模拟器截图）

界面代码：

<view class="container">

<map id="myMap" latitude="{{latitude}}" longitude="{{longitude}}" scale="{{scale}}" markers="{{markers}}" bindmarkertap="bindmarkertap" polyline="{{polyline}}" bindregionchange="bindregionchange" show-location>
