Registered event being dispatched twice since v11.9.0

Description

Since 11.9.0, the event Registered dispatched on RegisteredUserController is being listened twice, so this test:

<?php

use App\Notifications\WelcomeNotification;

test('new users can register', function () {
    Notification::fake();

    $response = $this->post('/register', [
        'name' => 'Test User',
        'email' => 'test@example.com',
        'password' => 'password',
        'password_confirmation' => 'password',
    ])->dump()->assertNoContent();

    $this->assertAuthenticated();
    $response->assertNoContent();

    Notification::assertSentTimes(WelcomeNotification::class, 1);
});

started to fail: Tests\Feature\Auth\RegistrationTest > new users can register Expected [App\Notifications\WelcomeNotification] to be sent 1 times, but was sent 2 times. Failed asserting that 2 is identical to 1.

While writing this issue I noted that this only occurs if the argument $event in the listener has the explicit type, like handle(Registered $event)

Steps To Reproduce

• composer create-project laravel/laravel:^11.9 example-app
• composer require laravel/breeze
• php artisan breeze:install
• choose api, pest
• modify Tests\Feature\Auth\RegistrationTest to be like the provided code in the description step
• php artisan make:notification WelcomeNotification
• php artisan make:listener SendWelcomeNotification

<?php

namespace App\Listeners;

use App\Notifications\WelcomeNotification;
use Illuminate\Auth\Events\Registered;

class SendWelcomeNotification
{
    public function handle(Registered $event): void
    {
        $event->user->notify(new WelcomeNotification());
    }
}

• note that the event argument has the explicit 'Registered' type, if I remove it, the test passes again

So it's like the type before $event is dispatching the event again? I mean, this is not the behavior prior v11.9.0, the test pass in v11.8.0 and below.

Seems like the same as #51610. Are you using the EventServiceProvider directly in v11? See https://laravel.com/docs/11.x/releases#service-providers

No, my bootstrap/app.php has only AppServiceProvider, but I was registering the event/listener in AppServiceProvider with:

Event::listen(Registered::class, SendEmailVerificationNotification::class);
Event::listen(Registered::class, SendWelcomeNotification::class);
Event::listen(WebhookReceived::class, StripeEventListener::class);

removing it from AppServiceProvider and running the test agains, It passes like it was in v11.8 and previous versions.

Yes that is the expected behaviour now.
