title: How to show focus in wp_editor of wordpress metabox
body: <p>I added tinyMCE editor via wp_editor() to post metabox.
  I want the focus inside the editor to be maintained when i switch between the visaul and text tab. (same as post editor)</p>
  <p>For now, when I drag a specific sentence from the visual tab and move to the text tab, the focus disappears.</p>
  <p>If anyone knows a solution please let me know.</p>
  <p>I am using wp version 4.9.20.
  Here is my wp_editor() usage.</p>
  <pre><code>$meta_key = '_my_meta_key'; 
  $meta_value = get_post_meta($post-&gt;ID, $meta_key, true); 
  $settings = array('textarea_name' =&gt; $meta_key, 'media_buttons' =&gt; false); 
  wp_editor($meta_value, 'my_custom_editor', $settings);
  </code></pre>
