a trick to remove a set of known keys: https://www.php.net/manual/en/function.array-filter.php#87912

But actually, better, array filter itself has a flag to use keys for the filtering now, https://www.php.net/manual/en/function.array-filter.php

Anyway, after the truly awful forced rendering stuff, which has got to be undone sometime, comes the nifty filtering bit:

  $raw_programs = node_view_multiple(array_map($map, $result->getResultItems()), 'teaser');
  // NOT a hack i like, but it's the only way i can get these nodes to not just render as empty shells
  // (really! it printed the template without any of the text).  This seems to be related to prerender:
  // https://www.drupal.org/project/drupal/issues/2099131
  // https://www.drupal.org/project/drupal/issues/2151459
  render($raw_programs);
  $programs = array_filter($raw_programs, function ($key) { return substr($key, 0, 1) !== '#'; }, ARRAY_FILTER_USE_KEY);
