ulAttr(['class' => 'sitemap']) - does not work

[DmitrySkibitsky]

Previously worked. Now there is no specified class in the generated layout.

php "atayahmet/laravel-nestable": "^0.8.0"

$result = \Nestable::make($prepare_data);
$result->ulAttr(['class' => 'sitemap'])->route(['categories/update' => 'id'])->renderAsHtml();

dump

Class seems attached to inner <ul> element. am i wrong? Also the package last version 8.6

[DmitrySkibitsky]

It used to be so

now it does not assign a class to the parent ul

composer.json

        "php": ">=7.1.0",
        "atayahmet/laravel-nestable": "^0.8.6",

I regularly check for updates

ulAttr(['class' => 'sitemap']) - This method used to work differently. And I think now it does not work properly
