title: Component Angular have size (Width Height)
body: <p>I have an issue in Angular 4.</p>
  
  <p>I thinks component in angular doesn't have size (width x height) like this:</p>
  
  <p><img src="https://i.stack.imgur.com/x8OYp.png" alt="Angular issue"></p>
  
  <p>So I can't render new component because old component is still there, I can't change value of this.</p>
