Test assertSee and hidden modal

Ia have a modal create form:

<div id="edit-form" x-data x-cloak
         x-show="$wire.showEditForm">Some Content</div>

It is hidden by default:

public bool $showEditForm = false;

Visibility is toggled with action on button:

<button type="button" wire:click="create" wire:loading.attr="disabled">Open modal</button>

Create and showEditForm methods:

public function create(): void
    {
        $this->showEditForm();
    }

 private function showEditForm(): void
    {
        $this->showEditForm = true;
    }

All works fine, but my test passes, even without calling create to open modal and render it:

public function test_add_new_form_modal_can_be_rendered()
    {
        Livewire::test(MyForms::class)
//            ->call('create')
            ->assertSee(__('Save'));
    }

Here I'm testind, that the Save button in my modal form is rendered. If I remove form from the template totally, test fails. Why does the test passes?
