HarmonyOS 鸿蒙Next getTarget()接口获取原始对象不正确问题，不知是何原因？难道是bug？
开发示例中，用getTarget()接口获取状态管理框架前代理对象有问题，实际上机测试时，比对结果和示例结果不符（示例结果为true,上机运行结果是falst）：如

import { UIUtils } from '@kit.ArkUI';

@Observed
class ObservedClass {
  name: string = "Tom";
}

class NonObservedClass {
  name: string = "Tom";
}

let observedClass: ObservedClass = new ObservedClass(); // 被代理
let nonObservedClass: NonObservedClass = new NonObservedClass(); // 不被代理
let globalNumberList: number[] = [1, 2, 3]; // 不被代理
let globalSampleMap: Map<number, string> = new Map([[0, "a"], [1, "b"], [3, "c"]]); // 不被代理
let globalSampleSet: Set<number> = new Set([0, 1, 2, 3, 4]); // 不被代理
let globalSampleDate: Date = new Date(); // 不被代理

@Entry
@Component
struct Index {
  @State observedObject: ObservedClass = observedClass; // 已被代理数据不会重复创建代理
  @State nonObservedObject: NonObservedClass = nonObservedClass; // 创建代理
  @State numberList: number[] = globalNumberList; // Array类型创建代理
  @State sampleMap: Map<number, string> = globalSampleMap; // Map类型创建代理
  @State sampleSet: Set<number> = globalSampleSet; // Set类型创建代理
  @State sampleDate: Date = globalSampleDate; // Date类型创建代理
  
  build() {
    Column() {
      Text(`this.observedObject === observedClass: ${this.observedObject === observedClass}`) // true
      
      Text(`UIUtils.getTarget(this.nonObservedObject) === nonObservedClass: ${UIUtils.getTarget(this.nonObservedObject) === nonObservedClass}`) // true 上机实际结果为false
      
      Text(`UIUtils.getTarget(this.numberList) === globalNumberList: ${UIUtils.getTarget(this.numberList) === globalNumberList}`) // true
      
      Text(`UIUtils.getTarget(this.sampleMap) === globalSampleMap: ${UIUtils.getTarget(this.sampleMap) === globalSampleMap}`) // true 上机实际结果为false
      
      Text(`UIUtils.getTarget(this.sampleSet) === globalSampleSet: ${UIUtils.getTarget(this.sampleSet) === globalSampleSet}`) // true 上机实际结果为false
      
      Text(`UIUtils.getTarget(this.sampleDate) === globalSampleDate: ${UIUtils.getTarget(this.sampleDate) === globalSampleDate}`) // true 上机实际结果为false
    }
  }
}
