`SlevomatCodingStandard.Namespaces.UnusedUses` cannot handle properties with (nullable) intersection types

SlevomatCodingStandard.Namespaces.UnusedUses thinks the imports are unused when property contains (nullable) intersection types.

This code:

<?php

namespace App;

use Symfony\Component\Cache\Adapter\AdapterInterface;
use Symfony\Contracts\Cache\CacheInterface;

class Example
{
    public (AdapterInterface&CacheInterface)|null $cache = null;
}

Results in the following output:

FILE: example.php
-------------------------------------------------------------------------------------------------

I am using squizlabs/php_codesniffer@3.7.2 and slevomat/coding-standard@8.14.1

Does any have any ideas how to fix this?
