title: How can you return status code 404 from angular PageNotFoundComponent?
body: <p>My understanding is that you can customize the not found page by setting <code>{ path: '**', component: PageNotFoundComponent }</code> to RouterMoudle.forRoot(routes).</p>
  
  <p>However it returns http status code 200.
  How can you return status code 404?</p>
