Incorrect formatting for comma-separated use statement

[theodorejb]

Code sample

<?php

namespace Bar;

use DateTimeImmutable, DateTimeZone;

class Foo
{
}

To reproduce

1. Create a file called Foo.php with the code sample above...
2. Run phpcs --standard=PSR12 Foo.php
3. See error message displayed

 5 | ERROR | [x] Header blocks must be separated by a single blank line

Expected behavior
No error.

Versions:

• OS: Windows 11
• PHP: 8.1
• PHPCS: 3.7.1
• Standard: PSR12

Additional context
If I run phpcbf --standard=PSR12 Foo.php, it formats the file as follows:

<?php

namespace Bar;

use DateTimeImmutable,

DateTimeZone;

class Foo
{
}

This does not appear to match the PSR-12 specification, and it makes no sense anyway given that an import like the following is correctly left on one line without any error:

use Package\{ClassA, ClassB};
