"Pattern Views row plugin does not support preview." in ajax rendered view

I commented, in the following file `ui_patterns_views.module` lines 53 to 56

//  if ($view->preview && !isset($view->element['#embed'])) {
//    \Drupal::messenger()->addWarning(t('Pattern Views row plugin does not support preview.'));
//    $variables['pattern'] = ['#type' => 'status_messages'];
//  }
  /*else*/

And it seams to work.
But I'd like to know why you disables preview for patterns ? For perf? Other reason ?

Regards.

My ugly quick and dirty diff.
No warranty !
