   * Config entities are not cached and there is no easy way to enable static
   * caching. See: Issue #1885830: Enable static caching for config entities.
   *
   * Overriding just EntityStorageBase::load is much simpler
   * than completely re-writting EntityStorageBase::loadMultiple. It is also
   * worth noting that EntityStorageBase::resetCache() does purge all cached
   * yamlform config entities.
   *
   * Forms need to be cached when they are being loading via
   * a form submission, which requires a form's elements and meta data to be
   * initialized via YamlForm::initElements().
