Indicate publication status on the taxonomy overview page

As a workaround, here's what I added to a custom module:

/**
 * Implements hook_form_FORM_ID_alter() for taxonomy_overview_terms.
 */
function MYMODULE_form_taxonomy_overview_terms_alter(&$form, FormStateInterface &$form_state, $form_id) {
  foreach ($form['terms'] as $key => &$value) {
    if (is_array($value) && isset($value['term']) && is_array($value['term'])) {
      if (!empty($value['term']['tid']['#value'])) {
        $term = Term::load($value['term']['tid']['#value']);
        if (empty($term->status->value)) {
          $value['#attributes']['class'][] = 'term--unpublished';
        }
      }
    }
  }

  $form['terms']['#attached']['library'][] = 'MYMODULE/admin_tweaks';
}

MYMODULE.libraries.yml has this:

admin_tweaks:
  css:
    component:
      css/admin-tweaks.css: { }

css/admin-tweaks.css has this:

.term--unpublished {
  background-color: #fff4f4;
}

Hope this helps someone else.

I am closing as it seems a duplicate of #3359159 ✨ Add Status to OverviewTerms.php form Fixed which was solved some time back.

Actually reading at the exact title and the workaround, it seems more a visual indication which is requested here.

If we decide to so, it should be consistent with other places we list entities with "Status" column.
