HarmonyOS WaterFlow滚动到中间重构Sections导致组件异常重复渲染

WaterFlow滚动到中间重构Sections导致组件异常重复渲染。操作步骤如下:

1、将waterFlow滑动到双列流位置。

2、刷新商品触发waterFlow的Sections被重建。

3、屏幕外的FlowItem疯狂刷新。

4、最后导致主线程卡死,内存溢出crash日志如下:

需要保证LazyForEach下每一个FlowItem的key唯一性,不能重复。如果reload了所有FlowItem的数据,希望新旧数据的key可以重复,组件不重建只刷新UI,可以使用ObjectLink只更新组件中的数据。
