Refresh组件不支持设置nestedScroll属性

@Entry 
@Component 
struct Index { 
  @State isRefreshing: boolean = false 
 
  build() { 
    Stack() { 
      List() { 
        ListItem() { 
          Stack().height(500).width('100%').backgroundColor(Color.Red) 
        } 
 
        ListItem() { 
          Column() { 
 
            Refresh({ refreshing: $$this.isRefreshing }) { 
              List() { 
                ListItem() { 
                  Stack().height(100).width('100%').backgroundColor(Color.Black) 
                } 
 
                ListItem() { 
                  Stack().height(100).width('100%').backgroundColor(Color.Pink) 
                } 
              } 
              .nestedScroll({ 
                scrollForward: NestedScrollMode.PARENT_FIRST, 
                scrollBackward: NestedScrollMode.PARENT_FIRST 
              }) 
              .height('100%') 
            } 
            .onRefreshing(() => { 
              setTimeout(() => { 
                this.isRefreshing = false 
              }, 2000) 
              console.log('onRefreshing test') 
            }) 
          }.height(500) 
        } 
      } 
    } 
    .width('100%').height('100%')
