【报Bug】vue3版本情况下，编译到微信小程序端 使用插槽报错

示例代码：

<uni-nav-bar :fixed="true" :statusBar="true">  
            <block slot="left">  
                <view class="city">  
                    <view>  
                        <text class="uni-nav-bar-text">{{ shopName }}</text>  
                    </view>  
                    <uni-icons type="arrowdown" color="#666" size="18" />  
                </view>  
            </block>  
        </uni-nav-bar>

操作步骤：

<uni-nav-bar :fixed="true" :statusBar="true">  
            <block slot="left">  
                <view class="city">  
                    <view>  
                        <text class="uni-nav-bar-text">{{ shopName }}</text>  
                    </view>  
                    <uni-icons type="arrowdown" color="#666" size="18" />  
                </view>  
            </block>  
        </uni-nav-bar>

预期结果：

正常编译，自定义导航栏左侧显示我想要的内容

实际结果：

不显示、并且控制台报错
