点击手风琴内的项目时，模态框左侧滚动条返回顶部的问题有解决方案吗？

Question

在初始加载中，如果我单击“销售”手风琴，然后单击“报告和预测的总销售额”，标记的滚动条将跳到顶部

标记的 ng-container 用于报告和预测总销售额 UI

以下是总报告和预测销售 UI 的 HTML

Answer 1

<div mat-dialog-content class="matContent" *ngIf="filter.filterGroupKey === 'drugReportedSalesAndForecastGroup'" preserve>
  </div>

添加preserve并检查是否有效
