【报Bug】禁用原生导航栏之后slider的changing事件会失效

补充代码：
page:

<template>  
    <view class="content" style="padding-top: 200upx;">  
        <view>  
            <slider @changing="changing" min="50" max="200" show-value/>  
        </view>  
    </view>  
</template>  

<script>  
    export default {  
        data() {  
            return {  
            }  
        },  
        methods: {  
            changing(e){  
                console.log(e.detail.value)  
            }  
        }  
    }  
</script>  

<style>  

</style>  

pages.json

{  
    "pages": [ //pages数组中第一项表示应用启动页，参考：https://uniapp.dcloud.io/collocation/pages  
        {  
            "path": "pages/index/index",  
            "style" : {  
                "navigationBarTitleText" : "xxxx",  
                "app-plus" : {  
                    "titleNView" : false,  
                    "bounce" : "none",  
                    "scrollIndicator" : "none"  
                }  
            }  
        }  
    ],  
    "globalStyle": {  
        "navigationBarTextStyle": "black",  
        "navigationBarTitleText": "uni-app",  
        "navigationBarBackgroundColor": "#F8F8F8",  
        "backgroundColor": "#F8F8F8"  
    }  
}
