title: TFS WorkItem Layout problem
body: <p>I'm customizing a TFS Work Item Type, adding a 'Business Description' HTML Field, but I cannot get the Layout right:</p>
  
  <pre><code>      &lt;Tab Label="Details"&gt;
          &lt;Group&gt;
            &lt;Column PercentWidth="60"&gt;
              &lt;Control FieldName="Customer.BusinessDescription" Type="HtmlFieldControl" Label="Business Description:" LabelPosition="Top" Dock="Fill" /&gt;
            &lt;/Column&gt;
            &lt;Column PercentWidth="40"&gt;
              &lt;Control FieldName="Microsoft.VSTS.CMMI.Symptom" Type="HtmlFieldControl" Label="Symptom:" LabelPosition="Top" /&gt;
              &lt;Control FieldName="System.History" Type="WorkItemLogControl" Label="&amp;amp;History:" LabelPosition="Top" /&gt;
            &lt;/Column&gt;
          &lt;/Group&gt;
        &lt;/Tab&gt;
  </code></pre>
  
  <p>This turns out like this:

  <p>While I really want this ('Photoshopped' with MSPaint):
  <img src="https://i.stack.imgur.com/XPV29.png" alt="desired layout"></p>
  
  <p>I have played around with the Fill properties on all three fields, have already set the MinimumSize property on the BusinessDescription field, added a group inside the left column, but I do not seem to find a solution for this.</p>
  
  <p>Is this at all possible?</p>
