title: Disable autosuggestion tags in admin area Wordpress
body: <p>I have about 50M tags for Posts. Its annoying to work with Post when add tags autocomplete can freeze browser. Is any native function to disable autosuggestion tags?
  I try this way but it disable tags functionality at all:</p>
  <pre><code>    add_action( 'init', 'disable_auto_tag_suggestion' );
  function disable_auto_tag_suggestion() {
      wp_deregister_script( 'suggest' );
  }
  </code></pre>
