Minimal PHP Code Causing Issue

<?php
declare(strict_types=1);

namespace Modules\Set\Tests\Unit\Http\Controllers\Traits;

use Modules\Core\Tests\TestCase;
use ReflectionClass;

class SupportsSetSourceControllerTest extends TestCase
{
    public function testGetSetItems(): void
    {
        $reflectionClass = new ReflectionClass('SomeClass');
        $method = $reflectionClass->getMethod('getSetItems');
        $method->setAccessible(true);
        $method->invoke($this->traitMock, 'some-param', 4, 5, 6);
    }
}

Expected Behaviour

Since the method signature of ReflectionMethod::invoke is public ReflectionMethod::invoke ( object $object [, mixed $... ] ) : mixed and the doc (https://php.net/manual/en/reflectionmethod.invoke.php) states Zero or more parameters to be passed to the method, it accepts a variable number of parameters which are passed to the method. You'd expect multiple parameters (beyond the two from the signature) to be accepted. In this case though, any parameter beyond the first two is reported as unnecessary and removed.
