title: Remove Focus/Blur on Select programmatically (Angular6 Material)
body: <p>I duplicated the Angular 6 Material autocomplete simple example:
  <a href="https://stackblitz.com/angular/brrjvqvprrbv?file=app%2Fautocomplete-simple-example.ts" rel="noreferrer">Simple Autocomplete</a></p>
  
  <p>I am trying to figure out how remove focus once selection has been made.</p>
  
  <p>I have added the following change:</p>
  
  <p>In HTML</p>
  
  <pre><code>&lt;mat-autocomplete #autoGroup="matAutocomplete" (optionSelected)="onSelectionChanged($event)"&gt;
  </code></pre>
  
  <p>In Components</p>
  
  <pre><code>  onSelectionChanged(event: MatAutocompleteSelectedEvent) {
      console.log(event.option.value);
    }
  </code></pre>
  
  <p>After it outputs the value  to console i would like to remove the focus from the input field, but not sure the way to do this.</p>
