Ionic scroll to item with Virtual Scroll

I have a list with big data.
In order to make the scrolling not lag, I am using Virtual Scroll, like this:

<ion-list [virtualScroll]="sections">
    <div  *virtualItem="let section" class="section" [attr.id]="section.chapterNum">
      <h4 *ngIf="section.Chapter !=''"></h4>
      <h5 [ngClass]="section.Section_Title"></h5>
      <div [innerHTML]="section.Section_Body | sanitizeHtml"></div>
    </div>
</ion-list>

I also have a need for jumping to specific parts of the list, which I did like this (before applying the Virtual Scroll):

GoToSection(chapter: number, section: string) {
    this.menuCtrl.close();
    var el = document.getElementsByClassName(section);
    let yOffset;
    for (var i = 0; i < el.length; i++) {
      if (+el[i].parentElement.id == chapter) {
        yOffset = (el[i] as HTMLElement).offsetTop;
      }
    }
    setTimeout(() => {
      this.content.scrollTo(0, yOffset, 0)
    }, 300);
}

However, when I try to use this method, it shows a blank screen, since it didn't render the scrolled element yet and couldn't find it.
Is there a different way to scroll to an element with Virtual Scroll?

If not, is there an alternative option to Virtual Scroll? (Infinite Scroll isn't an option)
