Widgets: stylesheets are not enqueued when a WordPress widget is added to an Elementor page

### Prerequisites

- [X] I have searched for similar issues in open and closed tickets and cannot find a duplicate.
- [X] I have troubleshooted my issue, and it still exists against the latest stable version of Elementor.

### Description

Plugins can register WordPress widgets using the Widgets API (`register_widget` and extending the `WP_Widget` class). When they do that, they can enqueue scripts and styles for their widget, by hooking `wp_enqueue_scripts`. A good practice when enqueuing custom scripts and styles is to only enqueue them when the widget is present on the page. That can be checked with the `is_active_widget` feature. Unfortunately, `is_active_widget` does not return `true` on pages where a widget has been added to the page via the Elementor editor

### Steps to reproduce

1. Start by installing the latest version of the Elementor plugin.
2. Add a plugin that registers a widget on the site. That widget must enqueue custom styles like so:

```php
'My widget description',
'customize_selective_refresh' => true,
'show_instance_in_rest' => true,
)
);

$this->default_title = 'My widget description';

if ( is_active_widget( false, false, $this->id_base ) || is_customize_preview() ) {
add_action( 'wp_enqueue_scripts', array( $this, 'enqueue_style' ) );
}
}

/**
* Enqueue stylesheet.
*/
public function enqueue_style() {
wp_register_style(
'my-custom-widget',
plugins_url( 'style.css', __FILE__ ),
array(),
'20241017'
);
wp_enqueue_style( 'my-custom-widget' );
}

... Rest of the widget registration and display logic.
}
```

3. Go to Pages > Add New
4. Open the Elementor Editor
5. Add a new container.
6. In that container, add our WordPress widget (scroll down to the "WordPress" part of the inserter, you should see the custom widget there)
7. Publish the page.
8. View it on the frontend.

### Expected behavior

I would expect my stylesheet to be enqueued on the page since the widget is present there. Unfortunately, it is not enqueued until I remove the `is_active_widget` check.

### Isolating the problem

- [ ] This bug happens when only the Elementor (and Elementor Pro) plugins are active.
- [ ] This bug happens with the Hello Elementor theme active.
- [X] I can reproduce this bug consistently by following the steps I described above.
