Livewire 3 - assetUnauthorized() doesn't work

Hello,

I have written a test to check that a user cannot create a category.

/** @test */
public function user_cannot_create_a_category(): void
{
    $user = User::factory()->create();

    $this->assertEquals(0, Category::count());

    Livewire::
        actingAs($user)
        ->test(Categories::class)
        ->set('form.name', 'Une catégorie')
        ->call('save')
        ->assertUnauthorized();

    $this->assertEquals(0, Category::count());
}

The test is aborted and I get this error.

Illuminate\Auth\Access\AuthorizationException: This action is unauthorized.

Wheras when I check that an admin can create a category, it works fine.

I specify that I have checked the authorization in the Livewire controller inside the save() method.

Categories component

public function save()
{
    $this->form->save();
    $this->showModal = false;
}

CategoryForm

public function save()
{
    if ($this->id) {
        $this->update();
    } else {
        $this->store();
    }
    $this->reset(); 
}

public function store()
{
    $this->authorize('create', Category::class);
    $this->cleanFields();
    $validated = $this->validate();

    $category = new Category;
    $category->fill($validated);
    $category->save();
}

Is it a bug or do I have forgotten something ?

Thanks for your help.
