app nvue页面引入vue悬浮可拖拽组件，@touchstart事件获取不到clientY和clientX

uni-app nvue页面引入vue悬浮可拖拽组件，@touchstart事件获取不到clientY和clientX，HbuliderX使用的是最新版的3.2.9，请问是什么原因呢？？？？

悬浮组件组件代码：  
<template>  
    <view class="sa-hover-menu">  
        <!-- 开关按钮 -->  
        <view class="click-btn" @tap="show = !show" :style="{top: top+statusBarHeight + 'px' }" draggable="true"  
            @touchstart="touchstart" @touchend="touchend" @touchmove.stop.prevent="touchmove">  
            <image style="width: 140rpx;height: 50rpx;" v-if="show" src="/static/fasticon.png"></image>  
            <image style="opacity: 0.5;width: 80rpx;height: 50rpx;" v-if="!show" src="/static/fasticon_c.png">  
            </image>  
        </view>  
        <!-- 快捷导航 -->  
        <view class="major-box">  
            <view class="nav-box" :class="{show: show}" :style="{top: top+statusBarHeight+15 + 'px' }" draggable="true"  
                @touchstart="touchstart" @touchend="touchend" @touchmove.stop.prevent="touchmove">  
                <view class="nav-btn" v-for="(item, index) in btnList" :key="index" @tap="clickBtn(index)">  
                    <view class="nav-icon">  
                        <image style="width: 90rpx;height: 90rpx;" :src="item" error-icon="photo" mode="aspectFit">  
                        </image>  
                    </view>  
                </view>  
                <!-- 遮罩层 -->  
                <view class="mask" @tap="show = false" @touchmove.stop.prevent></view>  
            </view>  
        </view>  
    </view>  
</template>  

父页面为vue页面可以获取到：  
    "touches": [{  
        "pageX": 20.33333396911621,  
        "force": 1,  
        "identifier": 0,  
        "pageY": 184.33334350585938,  
        "clientY": 184.33334350585938,  
        "clientX": 20.33333396911621  
父页面为nvue页面值返回这些参数：  
"touches": [{  
        "screenY": 261.3333435058594,  
        "screenX": 20.33333396911621,  
        "pageX": 20.33333396911621,  
        "pageY": 9.333333015441895,  
        "identifier": 0  
    }],  
编辑模式：  
 "nvueStyleCompiler" : "uni-app",  
HbuliderX使用的是最新版的3.2.9，请问是什么原因呢？？？？
