Wrong result with Fibers PHP 8.1

STR

1) Run the script.

namespace AAA;

$mem = new \ArrayObject([1, 2, 3]);
$_SERVER = [];
unset($argc, $argv);

$fiber = new \Fiber(static function() use ($mem): void {
    echo "Run from the Fiber...\n";

    while (true) {
        $i = 100;
        while ($i--) {
            $mem->offsetSet('a'.random_int(0, 2000000), 10);
        }
        echo "Count ". $mem->count() ."\n";
        \Fiber::suspend();
    }
});

$mem = null;
unset($mem);

gc_collect_cycles();

$fiber->start();

$fiber->resume();
\meminfo_dump(\fopen('/tmp/mem_dump.json', 'w'));
$fiber->resume();

Actual result: ArrayObject is missing in the memory dump. Expected result: ArrayObject must be persist in the memory dump
