title: Why does hidden not work for dash_html_components.Label?
body: <p>When I try to hide a <code>dash_html_components.Label</code> with hidden, like this:</p>
  
  <pre><code>app.layout = html.Label('test',hidden=True)
  </code></pre>
  
  <p>I can still see the <code>Label</code>. But when I replace <code>Label</code> with <code>Div</code>, it does work. What could be the reason?</p>
  
  <p>They are not used in any Callbacks.
  Could the <code>Label</code>'s <code>style</code> maybe overwrite it? But then, why does it behave different for the <code>Div</code>?</p>
  
  <p>Thank you!</p>
