title: fromEvent not fire when I put HTMLElement, and fire when I put Jquery Object
body: <p><a href="https://stackblitz.com/edit/angular-ivy-zy4kg7" rel="nofollow noreferrer">Code Here</a></p>
  
  <p>If I put <code>$('input')</code> as parameter of <code>fromEvent</code> it will fire when I call <code>$('input').trigger('input')</code>. But if I put <code>document.getElementsByTagName('input')</code> as parameter it will not fire. It will fire only when I type, but not fire when I call <code>$('input').trigger('input')</code>.
  Can someone explain why?</p>
  
  <p>Note: <code>$('input').on('input', _ =&gt; console.log)</code> will work in both cases.</p>
