No summary for comment

The problem is here: https://git.drupalcode.org/project/rate/-/blob/3.0.x/src/Plugin/RateWidg...

This is workaround without module patch

/**
 * Implements hook_preprocess_HOOK().
 */
function MYMODULE_preprocess_rate_widgets_summary(&$variables) {
  if (isset($variables['vote'])) {
    /** @var \Drupal\votingapi\Entity\Vote $vote */
    $vote = $variables['vote'];

    if ($vote->getVotedEntityType() === 'comment') {
      $voting_service = \Drupal::service('plugin.manager.votingapi.resultfunction');
      if ($voting_service) {
        $results = $voting_service->getResults('comment', $vote->getVotedEntityId());
        if ($results) {
          $variables['rate_count'] = $results['updown']['vote_count'];
          $variables['rate_sum'] = $results['updown']['vote_sum'];
        }
      }
    }
  }
}

And then use new variables in your summary template
