Livewire 3 project not working without deprecated @livewireStyles @livewireScripts old directives

Hi guys. I found something strange. I have a project with Laravel 3, that does not updates the input tag with the variable change. It works from the view to the component, but not the other way round. So, I did a project from scratch, for test purposes, with Laravel 11 and Livewire 3, and here comes the question. This new project didn't work, the updatedFoo event didn't fire. So, after 6 hours of trying, I added @livewireStyles @livewireScripts and it started working! Why, if they are not required in Livewire 3 anymore? Livewire version: 3.4.10.

THE BLADE VIEW (if I remove Styles and Scripts, it DOES NOT work, no updating, no lifecycle, no connection).

@livewireStyles
@livewire('prueba')
@livewireScripts

THE LIVEWIRE COMPONENT

<?php

namespace App\Livewire;

use Livewire\Component;

class Prueba extends Component
{
    public $name, $description;

    public function updatedName($value) //IT DOES NOT WORK WITHOUT @LIVEWIRESCRIPT-STYLE
    {
        $this->description = $value;
    }

    public function render()
    {
        return view('livewire.prueba');
    }
}

About that original (real) project, which only works one way, any ideas? This new project, with the directives, works both ways, the input is indeed updated when I update $name in the component. In my real project, the new value of the variable reaches the view (I use Xdebug), but the new value is not shown. I must say that in my real project I do NOT have the old directives, and the updatedFoo() method does work, to add more confusion.
