Cache context does not account for menu items that are not currently active but are in the active trail

In my menu, when a page loads that matches a menu link, all of the parents of that link (ie- all of the items in the active trail) get an an "active" class and are displayed as underlined. However, the cache context, LinkItemContentActiveTrailsCacheContext, returns "link_item_content.inactive" for these parents because they are not THE active link- they are only being checked against getActiveLink(), not checked to see if they are in the active trail:

$active_trail_link = $this->container->get('menu.active_trail')
      ->getActiveLink($menu_name);

    if ($active_trail_link && $active_trail_link->getDerivativeId() == $menu_link_id) {
      return 'link_item_content.active.' . $menu_link_id;
    }
    else {
      return 'link_item_content.inactive';
    }

Therefore, when a page is loaded for which these parent links are not part of the active trail, they are still in the 'link_item_content.inactive' context and, when read from cache, still have the 'active' class and display as underlined.
