Cannot use classes for PHP kata

[matks]

Describe the bug
It seems that when I use PHP classes for kata I get an error. As soon as there is a PHP class in the solution, it fails.

To Reproduce
If I input the following empty PHP code for kata
Conway's Game of Life - Unlimited Edition:

function get_generation(array $cells, int $generations): array {
  return [[]]; 
}

I run tests, I get, as expected, a PHPUnit error message 'Failed asserting that two arrays are equal.' because my code does not pass the tests.

Now I add an empty class below

function get_generation(array $cells, int $generations): array {
  return [[]]; 
}

class A {}

I re-run tests, I get a Error : Call to undefined function get_generation()

I can see this issue on another PHP kata.

Expected behavior
PHP Classes should be usable in a PHP kata.

Browser
Chrome, however issue was reproduced by another user and code is executed server-side. So I don't think browser informations are useful.

• OS: Mac OS X 11.5.2
• Browser: Chrome
• Version 93

Additional context
I wrote about this in discussion https://www.codewars.com/kata/52423db9add6f6fc39000354/discuss?#614ce089a155110033bb874b

It looks like it messes up test class name detection or something. Even a comment like // class A causes this. It happens it 8.0 and 7.4, but not in 7.0.
