Crashing on arguments with default value self::class

[e1himself]

Bug report

PHPStan crashes when trying to parse code with arguments having default value set to self::class.

<?php

class Service
{
	public static function createInstance(string $class = self::class): Service
	{
		return new $class();
	}
}

$service = Service::createInstance();

Internal error: Failed to find parent class of constant "class". Run PHPStan with --debug option and post the stack trace to: https://github.com/phpstan/phpstan/issues/new?template=Bug_report.md

This seems to be related to #4288, but not exactly.

Stack trace:
