鸿蒙蒸汽模式dispatchEvent无法传导事件参数

    private name : string | null = null    
    private $element : UniNativeViewElement;    
    private builder : BuilderNode<[NativeAmapOptions]> | null = null    
    // 初始化 buildButton 默认参数    
    private params : NativeAmapOptions = {    
        id: '',    
        // appKey: '',    
        showLocation: false,    
        owerIcon: '',    
        // name: '',    
        onReady: () => {    
            this.$element.dispatchEvent(new UniNativeViewEvent("isready", {}))    
        },    
        onMapClick: (point) => {    
            this.$element.dispatchEvent(new UniNativeViewEvent("mapclick", JSON.parseObject(JSON.stringify(point))!))    
        },    
        onCameraChange: (position) => {    
            this.$element.dispatchEvent(new UniNativeViewEvent("camerachange", JSON.parseObject(JSON.stringify(position))!))    
        },    
        onCameraChangeFinish: (position) => {    
            this.$element.dispatchEvent(new UniNativeViewEvent("camerafinish", JSON.parseObject(JSON.stringify(position))!))    
        },    
        onMarkerClick: (markerId) => {    
            let result = {    
                markerId: markerId    
            }    
            this.$element.dispatchEvent(new UniNativeViewEvent("markertap", JSON.parseObject(JSON.stringify(result))!))    
        }    
        // onClick: () => {    
        //  this.$element.dispatchEvent(new UniNativeViewEvent("customClick", {}))    
        // }    
    }    
    constructor(element : UniNativeViewElement) {    
        // 绑定 wrapBuilder 函数    
        this.builder = element.bindHarmonyWrappedBuilder(wrapBuilder<[NativeAmapOptions]>(buildAmap), this.params)    
        this.$element = element    
        // 绑定当前实例为自定义的controller，方便其他地方通过 element 获取使用    
        this.$element.bindHarmonyController(this)    
    }    
}```  

操作步骤：
在按照文档编写标准模式组件，在调用this.$element.dispatchEvent(new UniNativeViewEvent("mapclick", JSON.parseObject(JSON.stringify(point))!))中JSON.parseObject(JSON.stringify(point))!)是非空的

预期结果：
在自己的页面外部调用@mapclick时候可以像非蒸汽模式下正常收到数据

实际结果：
在自己的页面调用该标准模式组件中的@mapclick事件，能够正常触发，但收不到内容

bug描述：
在蒸汽模式下标准模式组件this.$element.dispatchEvent(new UniNativeViewEvent("camerafinish", JSON.parseObject(JSON.stringify(position))!))将参数传导出去，在自己的页面通过@camerafinish接收事件，可以触发事件但收不到传来的数据
