Batch hydrating job times out.

[ithuis]

i use the batch hydrating strategy described here
https://laravel.com/docs/10.x/queues#inspecting-batches

first layer is

    new LoadImportBatch,
])->then(function (Batch $batch) {
    // All jobs completed successfully...
})->name('Import Contacts')->dispatch();

the the loadImportBatch hydrates the batch like this

use App\Jobs\ImportContacts;
use Illuminate\Support\Collection;
 
/**
 * Execute the job.
 */
public function handle(): void
{
    if ($this->batch()->cancelled()) {
        return;
    }
 
    $this->batch()->add(Collection::times(1000, function () {
        return new ImportContacts;
    }));
}

but the "importContacts" job gets dispatched and the LoadImportBatch doesn't finish untile all the importContact jobs are done. When there to many, it wil eventually fail.
