### Description

The following code:

```php
<?php
class CustomDateTime extends \DateTime
{ }

$begin = new CustomDateTime('2012-08-01');
$end = new CustomDateTime('2012-08-31');
$period = new \DatePeriod($begin, new \DateInterval('P1D'), $end);
	
foreach ($period as $day) {
	echo get_class($day);
	exit;
}
```

Resulted in this output:
```
DateTime
```

But I expected this output instead:
```
CustomDateTime
```


This change in behaviour was introduced with a bug-fix release 8.1.9. It worked with 8.1.7.


### PHP Version

PHP 8.1.9
