uniapp x项目组件方面的两个问题

1.在同一个页面中，同时放置uni-upgrade-center-app和input组件（都是官方demo中的代码片段），input一旦单击获取焦点即闪退。

<uni-upgrade-center-app ref="upgradePopup"></uni-upgrade-center-app>  
<input class="uni-input uni-input-default" value="hello uni-app x" />

2.当picker-view的父级节点存在v-show时，切换v-show的状态时显示错乱，并且change事件的返回值错误并闪退。而将v-show切换为v-if则没有此问题。（因此将picker-view放进使用v-show来实现的弹出层中就会报错）

<view v-show="isOpen" style="width:100%;height: 500px;">  
    <picker-view class="picker-view" :indicator-style="indicatorStyle" :value="value" @change="bindChange" :mask-top-style="maskTopStyle" :mask-bottom-style="maskBottomStyle">  
        <picker-view-column class="picker-view-column">  
            <view class="item" v-for="(item,index) in years" :key="index"><text class="text">{{item}}年</text></view>  
        </picker-view-column>  
        <picker-view-column class="picker-view-column">  
            <view class="item" v-for="(item,index) in months" :key="index"><text class="text">{{item}}月</text></view>  
        </picker-view-column>  
        <picker-view-column class="picker-view-column">  
            <view class="item" v-for="(item,index) in days" :key="index"><text class="text">{{item}}日</text></view>  
        </picker-view-column>  
    </picker-view>  
</view>
