title: How to change the height of the a WPF `<Separator />`?
body: <p>I use the wpf  in a list menuitems in a normal menu (not the context menu).  </p>
  
  <p>Using the following style, the separator is not drawn:</p>
  
  <pre><code>&lt;Style x:Key="{x:Static MenuItem.SeparatorStyleKey}" TargetType="{x:Type Separator}"&gt;
      &lt;Setter Property="Height" Value="2" /&gt;
  &lt;/Style&gt;
  </code></pre>
  
  <p>The value of Height must <em>at least be 12,</em> but then the distance from menuitems is too large.</p>
  
  <p>What is happening here? Is it logical? Is there a solution?</p>
