title: Remove focus from mat-select after selection change
body: <p>In .html file i have selector:</p>
  <pre><code>&lt;mat-form-field&gt;
      &lt;mat-select #selector(selectionChange)=&quot;onSelectionChange($event.value)&quot;&gt;
        &lt;mat-option *ngFor=&quot;let test of tests&quot; [value]=&quot;test&quot;&gt;
        &lt;/mat-option&gt;
      &lt;/mat-select&gt;
    &lt;/mat-form-field&gt;
  </code></pre>
  <p>In .ts file I have:</p>
  <pre><code>  @ViewChild('selector', { static: false }) selector: MatSelect
  
    onSelectionChange(value: any) {
      this.selector.focused = false;
    }
  </code></pre>
  <p>It doesn't work because focused is read only parameter, but how to achieve this effect other way?</p>
