HarmonyOS 鸿蒙Next 自定义组件@BuilderParam 尾随闭包初始化后，链式调用属性时编译错误

@Component
struct MyButton {
  @Prop label: string
  @Builder closerBuilder(){
    Text('slot')
  };
  [@BuilderParam](/user/BuilderParam) closer: VoidCallback = this.closerBuilder

  build() {
    Button() {
      Row({space: 12}) {
        Text(this.label)
        this.closer()
      }
    }
  }
}

@Entry
@Component
struct ComponentsPage {
  
  @Builder
  iconText(text:string) {
    Text(text)
  }

  build() {
    Column({space: 12}) {
      // 这里 onClick 不会报错
      MyButton({label: '默认'}).onClick(() => { console.log('默认') })
      
      MyButton({
        label: '正常', 
        closer: () => this.iconText('☝')}
      ).onClick(()=> { console.log('正常') })
      
      // 这里 onClick 报错：Cannot find name 'onClick'. Did you mean the instance member 'this.onClick'?
      MyButton({label: '男性'}) {
        Text('♂')
      }.onClick(() => { console.log('男性') })
    }
  }
}

请问这是什么原因？哪里部分文档有说明这个问题。
