HarmonyOS 页面嵌套滑动时卡顿

示例参考如下：

@Entry
@Component
struct Index {

  private outerListScroller: ListScroller = new ListScroller();
  private innerListScroller: ListScroller = new ListScroller();
  private innerListScroller2: ListScroller = new ListScroller();
  private tabsController: TabsController = new TabsController();
  private topArr: number[] = Array(4).fill(1);
  private tabArr1: string[] = Array(20).fill("内层List第一个Tab的单元格");
  private tabArr2: string[] = Array(15).fill("内层List第二个Tab的单元格");

  build() {
    Column() {
      Text("我是标题区域") {

      }
      .backgroundColor(Color.Grey)
