title: Angular 7, Virtual Scroll. Can't set scrollTop in max
body: <p>Try to use Virtual Scroll for my chat. Work fine but I have a problem. When data loaded I set scrollTop in max to move to end the chat. But as a result, I am not at the end but almost in end (about 500px higher than bottom). Maybe some ideas on how to fix it? </p>
  
  <p>I use directive <code>CdkScrollable</code> from <code>'@angular/cdk/scrolling'</code>.</p>
  
  <p>Use it in a component like this:  </p>
  
  <pre><code>@ViewChildren(CdkScrollable) cdkScrollable;
  
  scrollToEnd() {    
      this.cdkScrollable.first.scrollTo({bottom: 0});
  }
  </code></pre>
