Caching issue with Brick content and CSS classes

I'm running into this same issue. Any advice on how you wrote your hook to clear it??

Hi Jenny - Here's a look at what we ended up implementing. It actually changed a little since I created this issue so that we could include nested bricks in the cache invalidation. You'll need to change the field machine name at the very least, but hopefully it helps!

/**
 * Implements hook_entity_presave().
 */
function mymodule_components_entity_presave(Drupal\Core\Entity\EntityInterface $entity) {
  if ($entity->getEntityType()->id() == 'node' && $entity->field_components !== NULL) {
    $bricks = $entity->field_components->referencedEntities();
    foreach ($bricks as $brick) {
      Cache::invalidateTags(array('brick:' . $brick->id()));
    }
  }
}
