wp_tag_cloud() and PHP 8

Hi, in a widget I want to use wp_tag_cloud() and I use it like this:

wp_tag_cloud( ‘smallest=1&largest=1&unit=em&number=18&orderby=count&order=DESC’ );

The problem is the “orderby=count” part. In the documentation it should be exactly like that but with PHP 8 on my server I get this warning:

Deprecated: uasort(): Returning bool from comparison function is deprecated, return an integer less than, equal to, or greater than zero in /www/htdocs/XXXXX/wp-includes/category-template.php on line 903

When I remove this part, it works fine. Is that a WordPress PHP 8 compatibility problem?

By the way, I use WordPress 5.9
