title: Possible bug in the Buefy navbar component
body: <p>Buefy navbar component is ignoring <code>mobile-burger</code> prop value.</p>
  
  <p>According to the documentation <a href="https://buefy.org/documentation/navbar/" rel="nofollow noreferrer">https://buefy.org/documentation/navbar/</a> navbar burger should not be displayed  on mobiles if this prop is false. But looks like it is not like this actually.</p>
  
  <pre><code>&lt;b-navbar mobile-burger="false"&gt;
              &lt;template slot="brand"&gt;
                  &lt;b-navbar-item href="/"&gt;
                      &lt;div class="logo-text" data-text="logo"&gt;logo&lt;/div&gt;
                  &lt;/b-navbar-item&gt;
              &lt;/template&gt;
  &lt;/b-navbar&gt;
  </code></pre>
  
  <p>I expected that if I set mobile-burger="false" then burger will not be displaying on mobiles. But I see no changes.</p>
  
  <p>Anyone know how to fix this ?</p>
