【报Bug】scroll-view轻轻往上一划就触发下拉刷新了？？希望官方demo能具体一点

示例代码：

<template>  
    <view>  
        <scroll-view  
            scroll-y  
            refresher-enabled  
            refresher-default-style="black"  
            refresher-background="#fff"  
            :refresher-triggered="regresherTriggered"  
            @scrolltolower="scrollBottomHandle"  
            @refresherrefresh="refresherrefreshHandle"  
            @refresherabort="refresherabortHandle"  
            @refresherrestore="refresherrestoreHandle"  
            @refresherpulling="refresherpullingHandle"  
            class="scroll-view-st"  
        >  
            <navigator url="./"><view v-for="item in dataList" :key="item.id" class="item-st">{{item.id}}</view></navigator>  
        </scroll-view>  
        <navigator open-type="navigateBack" :delta="1" class="sfs">back</navigator>  
    </view>  
</template>  

<script>  
let a = 0  
export default {  
    data() {  
        return {  
            regresherTriggered: false,  
            dataList: [],  
            loading: false,  
            freshing: false  
        }  
    },  
    onLoad() {  
        console.log('sss onload')  
        this.getList()  
    },  
    methods: {  
        // 滚定到底部触发  
        scrollBottomHandle() {  
            console.log('滚定到底部触发')  
            this.getList()  
        },  
        // 下拉刷新触发  
        refresherrefreshHandle() {  
            if (this.freshing) return  
            this.freshing = true  
            console.log('下拉刷新触发')  
            this.regresherTriggered = true  
            this.dataList = []  
            this.loading = false  
            a = 0  
            this.getList()  
        },  
        // 自定义下拉刷新被中止  
        refresherabortHandle() {  
            console.log('自定义下拉刷新被中止')  
        },  
        // 自定义下拉刷新被复位  
        refresherrestoreHandle() {  
            console.log(' 自定义下拉刷新被复位')  
            // this.regresherTriggered = 'restore'  
        },  
        // 自定义下拉刷新控件被下拉  
        refresherpullingHandle() {  
            console.log('自定义下拉刷新控件被下拉')  
        },  
        getList() {  
            console.log('调用了加载数据')  
            if (this.loading) return  
            this.loading = true  
            // this.regresherTriggered = true  
            setTimeout(() => {  
                console.log('请求道了数据')  
                let arr = []  
                a++  
                console.log('当前请求了第' + a + '页')  
                for (let i = 0; i < 15; i++) {  
                    arr.push({ id: `${a}-${i}` })  
                }  
                this.regresherTriggered = false  
                this.dataList = [...this.dataList, ...arr]  
                this.loading = false  
                this.freshing = false  
            }, 500)  
        }  
    }  
}  
</script>  

<style lang="scss">  
.scroll-view-st {  
    height: 100vh;  
}  
.item-st {  
    height: 180rpx;  
    background-color: green;  
    margin-bottom: 10rpx;  
}  
.sfs {  
    position: fixed;  
    left: 10rpx;  
    top: 50%;  
}
