【奇葩问题】vue 多个el-drawer 嵌套遮罩混乱问题解决方案，vue在＜el-drawer＞中嵌套＜el-drawer＞时遮罩bug 为了解决问题自己封装了一个简易的抽屉组件

<jw-drawer @change="change_data" :withheader="true" v-if="dialogVisible" :drawer='dialogVisible'
            size="60%" :title="dialogtitle">
            
</jw-drawer>

<template>
    <el-drawer :title="title" :visible.sync="drawer_show" :with-header="withheader" :size="size"
    
    direction="rtl" :before-close="handleClose" :style="{ right: (left==0 ? '0px':left) }" class="jwdranwer" :modal="false">
        <div class="eldrawerbody " :style="{ width: size, position: 'fixed', height: '100%' }">
            <el-button class="el_drawer_button" type="primary" icon="el-icon-close" @click="close"></el-button>
            <div class="help">
