title: Display sticky posts first with WP_Query and category__and
body: <p>Trying to display common posts from multiple post categories using WP_Query and category__and. Following is the query:</p>
  
  <pre><code>$query = array(
      'category__and' =&gt; array( 'cat-1', 'cat-2'),
      'posts_per_page' =&gt; 10,
      'paged' =&gt; $paged
      );
  
  $cat_query = new WP_Query($query);
  </code></pre>
  
  <p>Now in the above case the posts are correctly fetched but the sticky posts are not displayed first. </p>
  
  <p>Following code solves the problem but it doesn't perform "and" of the categories posts.</p>
  
  <pre><code>$query = array(
      'cat' =&gt; array( 'cat-1', 'cat-2'),
      'posts_per_page' =&gt; 10,
      'paged' =&gt; $paged
      );
  </code></pre>
  
  <p>The above query displays the sticky posts first but doesn't perform "and" on category posts.</p>
  
  <p>Is there any way to satisfy the condition of sticky posts first and common posts from multiple categories?</p>
