AtNavBar表现不正确

[qweasdzxcpkh]

问题描述
使用AtNavBar组件时出现非预期行为

复现步骤
taro init
使用Taro+vue, typescript，模板使用Taro-vue-ui模板

<template>
  <view class="index">
      <AtNavBar
        color="#000"
        leftIconType="chevron-left"
        rightFirstIconType='bullet-list'
      >
        navigation
      </AtNavBar>
  </view>
</template>

<script>
// 按需引入, 更小的应用体积
import { AtNavBar } from 'taro-ui-vue'
import "taro-ui-vue/dist/style/components/nav-bar.scss"
import "taro-ui-vue/dist/style/components/icon.scss"
import './index.less' 
export default {
  components: {
    AtNavBar,
  },
  data () {
    return {
    }
  },
}
</script>

若将

<AtNavBar
        color="#000"
        leftIconType="chevron-left"
        rightFirstIconType='bullet-list'
      >
        navigation
      </AtNavBar>

改为

<AtNavBar
        color="#000"
        leftIconType="chevron-left"
        rightFirstIconType='bullet-list'
      >
        <view>navigation</view>
      </AtNavBar>

则出现报错

期望行为
在小程序能呈现跟官方例子一样的效果
实际效果：

AtNavBar的嵌套子组件处理bug？
