title: phpDocumentor: DocBlock with @var tags duplicates descriptions
body: <p>I have this DocBlock in a php abstract class:</p>
  
  <pre><code>/**
  * @var string $foo a useful foo and &lt;code&gt;some.code()&lt;/code&gt; too
  * @var string $bar a useless bar
  *
  * @todo do something with &lt;code&gt;$this-&gt;bar&lt;/code&gt;
  */
  protected $foo, $bar;
  </code></pre>
  
  <p>I parsed this class with phpDocumentor; and here's the html result:
  <img src="https://i.stack.imgur.com/UbKz5.png"></p>
  
  <p>As you can see both <code>$foo</code> and <code>$bar</code> shares the same description (the $foo one) and markdown is not parsed too.
  On the other hand markdown of <code>@todo</code> tag is properly parsed.</p>
  
  <p>Where am I wrong?
  Did I miss something?</p>
  
  <p>I found a bug <a href="https://github.com/phpDocumentor/phpDocumentor2/issues/368" rel="nofollow noreferrer">ticket about markdown in <code>@var</code> tags</a>:
  Has it something to do with this issue maybe?</p>
