@LocalStorageLink和LocalStorage如何实现双向同步？

let para: Record<string, number> = { 'PropA': 47 };
let storage: LocalStorage = new LocalStorage(para);
let linkToPropA: SubscribedAbstractProperty<object> = storage.link('PropA');

@Entry(storage)
@Component
struct CompA {
   @LocalStorageLink('PropA') storageLink: number = 1;
  build() {
    Column() {
      Text(`incr @LocalStorageLink variable`)
        .onClick(() => {
          this.storageLink += 1
        })
      Text(`@LocalStorageLink: ${this.storageLink} - linkToPropA: ${linkToPropA.get()}`)
    }
  }
}
