Incorrect behavior when adding a message to a queue from a job

[Gree-k]

What steps will reproduce the problem?

Trying push message to queue from job.

class NotificationJob extends BaseObject implements JobInterface
{
    public function execute($queue)
    {
        $instances = $this->getInstances();
        foreach ($instances as $instance) {
            $queue->push(new SenderJob($instance));
        }
    }
}

$config = [
    'bootstrap' => ['queuePush'],
    'components' => [
        'queuePush' => [
            'class' => \yii\queue\amqp_interop\Queue::class,
            'host' => $rabbit['host'],
            'port' => $rabbit['port'],
            'user' => $rabbit['user'],
            'password' => $rabbit['pass'],
            'driver' => yii\queue\amqp_interop\Queue::ENQUEUE_AMQP_LIB,

            'queueName' => 'push',
        ]
    ],
];

supervisor config

[program:yii-queue-push]
process_name=%(program_name)s_%(process_num)02d
command=/usr/bin/php /var/www/project/yii queue-push/listen
autostart=true
autorestart=true
user=www-data
numprocs=10
redirect_stderr=true
stdout_logfile=/var/www/project/scripts/log/yii-queue-push.log

What's expected?

I expect that after the NotificationJob, the queue will get some SenderJob and then start executing them.

What do you get instead?

All SenderJob are executed in the NotificationJob and additionally added to the queue several times.

If you put SenderJob in another queue, where a $instances contains one array element.
The SenderJob will be executed and 3 messages will be added to the queuePushSend, although the SenderJob should not be executed and 1 message should be added to the queuePushSend.

class NotificationJob extends BaseObject implements JobInterface
{
    public function execute($queue)
    {
        $instances = $this->getInstances();
        foreach ($instances as $instance) {
            Yii::$app->queuePushSend->push(new SenderJob($instance));
        }
    }
}
