Superfish and Menu Token on multilingual site

I think, this is not a problem of superfish module, but menu_token module.
Menu token module overrides MenuLinkTree class to build the menu tree and replace token.
So, when MenuLinkTreeMenuToken class builds menu tree:
it gets the title like this:

$element['title'] = $link->getTitle();

but in this case we get title from MenuLinkContent class:

  /**
   * {@inheritdoc}
   */
  public function getTitle() {
    // We only need to get the title from the actual entity if it may be a
    // translation based on the current language context. This can only happen
    // if the site is configured to be multilingual.
    if ($this->languageManager->isMultilingual()) {
      return $this->getEntity()->getTitle();
    }
    return $this->pluginDefinition['title'];
  }

As you can see if the content is multilingual, then we take title from the entity and not from plugin definition.
Menu token modules replaces tokens only in the plugin definitions.

To conclude it should be correctly handled on Menu toke side then we will get the right value for a title.

I have just found this!
