【报Bug】vue3 下 picker-view-column v-if=false下，change返回的value值中数据仍有占位，造成数据错误

示例代码：

<template>  
    <view>  
        <picker-view :value="value" @change="bindChange" class="picker-view">  
            <picker-view-column v-if="false">  
                <view class="item" v-for="(item, index) in years" :key="item">{{ item }}年</view>  
            </picker-view-column>  
            <picker-view-column>  
                <view class="item" v-for="(item, index) in months" :key="item">{{ item }}月</view>  
            </picker-view-column>  
            <picker-view-column>  
                <view class="item" v-for="(item, index) in days" :key="item">{{ item }}日</view>  
            </picker-view-column>  
        </picker-view>  
    </view>  
</template>  
<script>  
export default {  
    data() {  
        const date = new Date();  
        const years = [];  
        const year = date.getFullYear();  
        const months = [];  
        const month = date.getMonth() + 1;  
        const days = [];  
        const day = date.getDate();  
        for (let i = 1990; i <= date.getFullYear(); i++) {  
            years.push(i);  
        }  
        for (let i = 1; i <= 12; i++) {  
            months.push(i);  
        }  
        for (let i = 1; i <= 31; i++) {  
            days.push(i);  
        }  
        return {  
            years,  
            months,  
            days,  
            // value: [9999, month - 1, day - 1],  
            value: []  
        };  
    },  
    methods: {  
        bindChange(e) {  
            const val = e.detail.value;  
            console.log(val);  
        }  
    }  
};  
</script>  
<style>  
.picker-view {  
    width: 750rpx;  
    height: 600rpx;  
    margin-top: 20rpx;  
}  
.item {  
    height: 39px;  
    align-items: center;  
    justify-content: center;  
    text-align: center;  
}  
</style>  

操作步骤：

滑动日期中的“日”，vue3情况下，因为change获取的e.detail.value值没有空白占位，且v-if=false下，column仍然有占位

预期结果：

在vue3下，picker-view的change事件获取的e.detail.value类似vue2下的正常数组，且picker-view-column v-if=false下，数组数据正常显示

实际结果：

在vue3下，picker-view的change事件获取的e.detail.value数组位数错误，且picker-view-column v-if=false下，数组仍然有占位。
