Identifier 'CustomPlugin' has already been declared

Description

Hi, I am working on a custom plugin on the latest version. It is loaded in a craft module following the documentation :

if (Craft::$app->getRequest()->getIsCpRequest()) {
    Plugin::registerCkeditorPackage(LexiqueAsset::class);
}

And it is a basic config like in the documentation :

class LexiqueAsset extends BaseCkeditorPackageAsset
{
    public $sourcePath = '@modules/ckeditor/resources/dist';

    public string $namespace = '@akufen/ckeditor5-akfn-lexique';

    public $js = [
        ['index.js', 'type' => 'module']
    ];

    public array $pluginNames = ['AkfnLexique'];
    public array $toolbarItems = ['akfnLexiqueButton'];
}

I have some CkEditor fields with different configurations loaded in different matrix block in the same page using the custom plugin.
As soon as I have 2 Ckeditor opened I get the following error :
Uncaught SyntaxError: Identifier 'AkfnLexique' has already been declared

and I can see in the dom :
import { AkfnLexique, AkfnLexique } from "@akufen/ckeditor5-akfn-lexique";

I am not sure if I am loading the custom plugin wrong or if maybe we could have a validation on your side like in craftcms/ckeditor/src/helpers/CkeditorConfig.php the registerPackage function could use a array_unique after the array_merge.

Additional info

• Craft version: 5.9.15
• PHP version: 8.4.17
