title: Parentheses disappear after formatting in vscode
body: <p>I write in vscode this statement in js:</p>
  
  <pre><code>   el.style.width = (this.elementWidth + round * 10) + "px";
  </code></pre>
  
  <p>After autosave / formatting (prettier) it turns to this:</p>
  
  <pre><code>   el.style.width = this.elementWidth + round * 10 + "px";
  </code></pre>
  
  <p>How do I change the settings to leave the parentheses without turning off prettier formatting?</p>
