No type in composer lson. lazysizes installing in vendor instead of libraries

https://www.drupal.org/docs/8/modules/lazy-load/how-to-use-composer-to-i... →

"extra": {
    "installer-types": ["bower-asset", "npm-asset"],
    "installer-paths": {
        ...
        "web/libraries/{$name}": ["type:drupal-library", "type:bower-asset", "type:npm-asset"],
        ...
    }
}

But composer.json of lazysizes library does not contains type attribute.
