【报Bug】uni-app nvue input标签用v-if控制显示隐藏时，前一个被隐藏的input中的值会被赋到后一个出现的input上

示例代码：

<template>
<view class="page">
<image src="../../static/logo.png" mode="" class="logo"></image>
<view class="account-login-way">
<view class="list" @click="tab_index=0">
<text class="text" :class="{active:tab_index==0}">账号密码登录</text>
<view class="border" :class="{active:tab_index==0}"></view>
</view>
<view class="list" @click="tab_index=1">
<text class="text" :class="{active:tab_index==1}">手机验证码登录</text>
<view class="border" :class="{active:tab_index==1}"></view>
</view>
</view>
<view class="input-group">
<text class="icon"></text>
<input class="input" type="number" v-model="user_phone" placeholder="请输入手机号"/>
</view>
<view class="input-group" v-if="tab_index==0">
<text class="icon"></text>
<input class="input" v-if="tab_index==0" type="password" v-model="user_pwd" placeholder="请输入密码"/>
</view>
<view class="input-group" v-if="tab_index==1">
<text class="icon"></text>
<input class="input" type="text" v-if="tab_index==1" v-model="check_code" placeholder="请输入验证码"/>
<view class="btn-send">
<text class="btn-text">发送验证码</text>
</view>
</view>
<view class="link-box">
<text class="left" @click="goForgetPassword">忘记密码？</text>
<text class="right" @click="goRegister">新用户注册</text>

操作步骤：

直接复制我上边的代码，把样式去掉，运行即可复现

预期结果：

密码框和验证码框不同时出现，且任意切换，输入的值不会被传递给下一个

实际结果：

估计是input索引错误，出现了bug
