Issue on styling anonymous class with parentheses

[tobigumo]

Q	A
Bug report?	yes
Feature request?	no
Library version	2.1.0

In anonymous class style, I expected, class keyword, one space, parentheses, one space and opening curly brace.
but actual, no one space after class keyword.

sample

test code

<?php
return new class {
    public function __construct(private $num)
    {
        $this->num = $num;
    }
};

expected

--- Original
+++ New
<?php
-return new class {
+return new class () {
    public function __construct(private $num)
    {
        $this->num = $num;
    }
};

actual

--- Original
+++ New
<?php
-return new class {
+return new class() {
    public function __construct(private $num)
    {
        $this->num = $num;
    }
};

reference

in PHP-CS-Fixer with @psr12 Rulesets,
'space_before_parenthesis' option is true

--- Original
+++ New
 <?php
-$foo = new class(){};
+$foo = new class () {};
