When I run your script, I only get *one* error output, not two.

Does not happen here:

$ php -v
PHP 7.4.20 (cli) (built: Jun  4 2021 21:24:37) ( NTS )
Copyright (c) The PHP Group
Zend Engine v3.4.0, Copyright (c) Zend Technologies
    with Zend OPcache v7.4.20, Copyright (c), by Zend Technologies
    with Xdebug v3.0.4, Copyright (c) 2002-2021, by Derick Rethans

$ cat error-test.php
<?php
set_error_handler(
     static function (int $severity, string $message, string $file, int
$line): void {
         throw new InternalErrorException($message, 0, $severity, $file,
$line);
     }
);
xxx();

$ php error-test.php

$ php error-test.php
PHP Fatal error:  Uncaught Error: Call to undefined function xxx() in
/home/arno/error-test.php:7
Stack trace:
#0 {main}
  thrown in /home/arno/error-test.php on line 7

So this is a local problem specific to your setup.
