// JOIN that we use in the asset.location service's getAssetsByLocation().
// 2. We need to allow other modules to override the asset.location service
// to provide their own location logic (eg: the Group asset module). They
// shouldn't have to override this Views argument handler as well.
// 3. It keeps this Views argument handler's query modifications very
// simple. It only needs the condition: "WHERE asset.id IN (:asset_ids)".
// See https://www.drupal.org/project/farm/issues/3217168 for more info.
