HarmonyOS 鸿蒙Next 使用半模态转场，弹出框中列表组件和当前滑动冲突问题解决

参考如下demo:

@Entry
@Component
struct SheetTransitionExample {

  @State isShow: boolean = false

  private arr: number[] = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]

  @Builder
  myBuilder() {
    Column() {
      List({ space: 20, initialIndex: 0 }) {
        ForEach(this.arr, (item: number) => {
          ListItem() {
            Text('' + item)
              .width('100%').height(100).fontSize(16)
              .textAlign(TextAlign.Center).borderRadius(10).backgroundColor(0xFFFFFF)
          }
        }, (item: string) => item)
      }.nestedScroll({
        scrollForward: NestedScrollMode.PARENT_FIRST,
        scrollBackward: NestedScrollMode.SELF_FIRST
      })
    }
  }

  build() {
    Column() {
      Button("transition modal 1")
        .onClick(() => {
          this.isShow = true
        })
        .fontSize(20)
        .margin(10)
        .bindSheet($$.isShow, this.myBuilder(), {
          detents:[SheetSize.MEDIUM, SheetSize.LARGE, 200],
          backgroundColor: Color.Green,
        })
    }
    .justifyContent(FlexAlign.Center)
    .width('100%')
    .height('100%')
  }
}
