list-view组件下拉刷新并不会复位

示例代码：

<template>

<list-view :refresher-enabled='true'  
    :refresher-triggered='refresh'  
    @refresherrefresh='refresherrefresh'  
    @refresherrestore="list_view_refresherrestore"  
    :show-scrollbar='false'>  
    <list-item class="item"  
        v-for="(item) in list">  
        <view>{{item}}</view>  
    </list-item>  
    <sticky-header>  
        <view class="item"  
            style="background-color: pink;margin-top: 0;">固定</view>  
    </sticky-header>  
    <list-item class="item"  
        v-for="(item) in list1">  
        <view>{{item}}</view>  
    </list-item>  
    <sticky-header>  
        <view class="item"  
            style="background-color: #000;margin-top: 0;">固定</view>  
    </sticky-header>  
    <list-item class="item"  
        v-for="(item) in list1">  
        <view>{{item}}</view>  
    </list-item>  
</list-view>  

</template>

<script>
type z = boolean
type s = string
export default {
data() {
return {
refresh: false as Boolean,
title: 'Hello' as string,
list: [] as Array<any>,
list1: [] as Array<any>
}
},
onLoad() {
for (let i : number = 0; i < 5; i++) {
this.list.push(i)
// this.list.push('1')
}
for (let i : number = 0; i < 20; i++) {
this.list1.push(i)
// this.list.push('1')
}
this.title = '222'
console.log(this.getData('3'))
},
methods: {
getData(c : s) : z {
let a = c;
let b = 3;
return a == b.toString()
},
refresherrefresh() {
setTimeout(() => {
this.refresh = false
console.log('关闭', this.refresh);
}, 2000)
},
list_view_refresherrestore() {
console.log('复位');
// setTimeout(() => {
// this.refresh = false
// console.log('关闭', this.refresh);
// }, 2000)
}
}
}
</script>

<style>
.content {
width: 100%;
}

.item {  
    width: 100vw;  
    height: 100rpx;  
    background-color: red;  
    margin-top: 20rpx;  
}  

</style>
