【报Bug】map组件下的customCallout里面包含cover-image ，app就会闪退

示例代码：

<template>  
    <view class="content">  
        <map id="map" :markers="covers" class="map" :show-location="true" :latitude="latitude" :longitude="longitude">  
            <cover-view slot="callout">  
                <template v-for="(item,index) in covers">  
                    <cover-view :marker-id="item.id" :key="item.id">  
                        <cover-image src="../../static/logo.png"></cover-image>  
                    </cover-view>  
                </template>  
            </cover-view>  
        </map>  
    </view>  
</template>  

<script>  
    const img = '/static/logo.png';  

    export default {

                }  
            });  

            this._mapContext.on("markerClusterCreate", (e) => {

                const markers = []  

                positions.forEach((p, i) => {  
                    const newMarker = Object.assign({}, marker, p)  
                    newMarker.id = i + 1

            }  
        }  
    }  
</script>  

<style>  
    .content {  
        flex: 1;  
    }  

    .map {  
        flex: 1;  
    }  
</style>

操作步骤：

新建nvue项目，复制代码示例里的代码运行即可

预期结果：

customCallout 出现图片

实际结果：

app闪退
