title: Tags not showing up while querying an ADX table
body: <p>If I fire <code>.show table &lt;TableName&gt; extents</code> I do see the list of extents with tags. But if I try to list those tags along with the table data I get blank, so the following query returns blank tags:-</p>
  
  <pre><code>&lt;TableName&gt; | extend tags=extent_tags() 
  </code></pre>
  
  <p>Why is it so ?</p>
