// Invokes infer_native_assets_yaml_isolate_spawnuri_2_helper.dart with
// `Isolate.spawn` and an explicitly passed package_config.json path.
//
// That subsequently invokes
// infer_native_assets_yaml_isolate_spawnuri_2_helper_2.dart with
// `Isolate.spawn` without a package_config.json path and without automatic
// package resolution, such that it will inherit the native assets yaml.
