HarmonyOS 鸿蒙Next 半模态弹框@State数据更改页面无法响应

HarmonyOS 鸿蒙Next 半模态弹框@State数据更改页面无法响应

用@Builder包裹一个组件，使用这个@Builder效果正常，将@Builder放到半模态效果不正常

demo如下

@Entry
@Component
struct SheetTransitionExample {
  [@State](/user/State) isShow: boolean = false

  [@Builder](/user/Builder)
  myBuilder() {
    SheetChild()
  }

  build() {
    Column() {
      this.myBuilder()
      Button("transition modal 1")
        .onClick(() => {
          this.isShow = true
        })
        .fontSize(20)
        .margin(10)
        .bindSheet($$this.isShow, this.myBuilder(), {
          height: '40%',
          backgroundColor: Color.Gray,
        })
    }
    .justifyContent(FlexAlign.Center)
    .width('100%')
    .height('100%')
  }
}

@Component
export struct SheetChild {
  [@State](/user/State) num: number = 1;

  build() {
    Row() {
      Button("-")
        .onClick(()=>{
          this.num--
        })
      Text(this.num.toString())
      Button("+")
        .onClick(()=>{
          this.num++
        })
    }
    .height(150)
    .width('100%')
  }
}
