我正在使用具有无限滚动功能的 ionic-selectable，我面临的问题是新页面数据加载，ionic-selectable 滚动移动到顶部。情况并非如此，用户应该看到新项目出现并继续正常滚动。

    <ion-item lines="none">
          <ionic-selectable #nationalityRef closeButtonSlot="end" formControlName="nationalities"
                  [items]="nationalities?.data" itemValueField="id" itemTextField="nationality" [canSearch]="true"
                  [searchPlaceholder]="'Profile.Form.Nationality' | translate" [hasInfiniteScroll]="true"
                  (onSearch)="searchThroughRecords($event,natl,false,'nationality')"
                  (onInfiniteScroll)="infinitescroll($event,true)" class="v2"
                  (onClose)="selectClosed(nationalityRef)">
                  <ng-template ionicSelectableTitleTemplate>
                    {{'Profile.Form.Nationality' | translate}}
                  </ng-template>
                  <ng-template ionicSelectablecloseButtonTemplate>
                    <ion-icon src="../../../assets/icon/close.svg"></ion-icon>
                  </ng-template>
                </ionic-selectable>
    </ion-item>

和班级代码：

    infinitescroll(event,record: paginatedResponse < any >,fn: CallableFunction,type ?: string,index ?: number) {
        const text = (event.text || '').trim().toLowerCase();
        // There're no more ports - disable infinite scroll.
        if (record.meta.current_page > record.meta.last_page) {
            event.component.disableInfiniteScroll();
            return;
        }
    
        const payload: any = {
            per_page: NationalityPerPage,page: record.meta.current_page,sort: 'title',direction: 'asc',nationality_id: null
        };
    
        fn(payload).subscribe((items: paginatedResponse<NationalitiesModel>) => {
            record.data = event.component.items.concat(items.data);
            event.component.items = record.data;
            event.component.endInfiniteScroll();
            record.meta.current_page++;
        });
    }
