Ckeditor fail to be initialized in newly added inline item (InlineModelAdmin)

[sveetch]

Summary

I'm facing the same old issue than #465 that was resolved years ago in #472. In summary when adding a new InlineModelAdmin item inside a plugin, the CKEditor fail to be initialized and the field is just a raw textarea.

Environment

• Python: 3.10
• Django: 5.0.7
• DjangoCMS: 3.11.6
• djangocms-text-ckeditor: 5.1.5

To Reproduce

1. Create a plugin with models Foo and FooItem where FooItem is related to Foo with a foreign keys, contain a field for a CKEditor content (with widget TextEditorWidget) and managed with InlineModelAdmin;
2. Add an object of this plugin in a page;
3. Open plugin edition;
4. Add a new item into plugin;
5. The CKeditor content field in newly added FooItem object is still a textarea;

Here is a simple video for demonstration:

record.webm

This results to this error in browser console:

With debugger just before error (using a debug breakpoint):

And in inspector for the newly added object:

We can see the JavaScript code attempts to use a id attribute but the payload from object is just an Array.

Expected behavior

Newly added inline admin items should have CKEditor properly initialized.

From what i have searched, it seems the commits from #472 was working well, it did not expected an id attribute to resolve field name:

https://github.com/vxsx/djangocms-text-ckeditor/blob/2364627726dfb1682aeefa1f7ab2d4972155e9f1/djangocms_text_ckeditor/static/djangocms_text_ckeditor/js/cms.ckeditor.js#L217

Opposed to master branch code that is expecting the attribute:

https://github.com/django-cms/djangocms-text-ckeditor/blob/master/djangocms_text_ckeditor/static/djangocms_text_ckeditor/js/cms.ckeditor.js#L431

I tried to patch my local bundle for the id attribute against Array, it worked but then it broke because of further code that attempt to reach other attributes like toolbar.
