function related_products_fix_query_brackets( $query )
{
    $query['where'] = preg_replace
    (
        "/\( tt.taxonomy = 'product_cat' AND t.term_id IN \([\s\S]+?\) \) OR \( tt.taxonomy = 'product_tag' AND t.term_id IN \([\s\S]+?\) \) AND p.ID NOT IN \([\s\S]+?\)/",
        '( $0 )',
        $query['where']
    );
    return $query;
