Update post term count

Hi there! Love this plugin, great work! One thing I noticed while playing around with it: When assigning attachments to terms, the term_count for those terms doesn’t update. This is due to attachments having the “inherit” post_status, and WordPress only respecting posts with post_status “publish” when counting posts in terms (more information here at update_count_callback). The following snippet solves this for me, maybe you could consider putting it in your plugin?

/**
 * Adds post_status 'inherit' to the term_count post statuses
 * 
 * @param array $statuses   the statuses (usually contains only 'publish')
 * @param \WP_Taxonomy      the taxonomy WordPress is counting posts for
 */
add_filter('update_post_term_count_statuses', function($statuses, $taxonomy) {
  if( in_array('attachment', $taxonomy->object_type) ) {
    $statuses[] = 'inherit';
  }
  return $statuses;
}, 10, 2);

I wrote the filter using an anonymous function for brevity, but you should get the idea. Hope it’s helpful.
