微信小程序端uni-list、uni-list-item使用v-for循环渲染报错

问题描述 [问题描述：尽可能简洁清晰地把问题描述清楚] 微信小程序端uni-list、uni-list-item使用v-for循环渲染报错但是不使用v-for循环渲染不报错。其他端正常【H5、Android下通过】 复现步骤 [复现问题的步骤] demo如下

<template>
  <view>
      <!-- 在v-for循环中使用会报错 -->
       <uni-list>
            <uni-list-item
                v-for="(item, i) in list"
                :key="i"
                :title="item.title"
                :show-extra-icon="true"
                :extra-icon="{ color: '#a8a8a8', size: '22', type: item.icon }"
                @click="item.go"
            ></uni-list-item>
        </uni-list>

        <!-- 不在v-for循环中使用不报错 -->
       <uni-list>
            <uni-list-item
                class="todo-list-item"
                :title="list[0].title"

预期结果 [使用简洁清晰的语言描述你希望生效的预期结果] 不报错 实际结果 [这里请贴上你的报错截图或文字] VM201:1 [Vue warn]: Property or method "item" is not defined on the instance but referenced during render. Make sure that this property is reactive, either in the data option, or for class-based components, by initializing the property.

系统信息:

发行平台: [如微信小程序、H5平台、5+ App等] 微信小程序
操作系统 [如 iOS 12.1.2、Android 7.0] 小程序开发者工具
HBuilderX版本 [如使用HBuilderX，则需提供 HBuilderX 版本号] 2.6.5.20200314
uni-app版本 [如使用Vue-cli创建/运行项目，则提供npm run info的运行结果]
设备信息 [如 iPhone8 Plus]

补充信息 [可选] [根据你的分析，出现这个问题的原因可能在哪里？] 原因可能是我把v-for放在了uni-list-item上。但是在其他端都通过了所以这应该还是bug
