details and fieldsets form elements

Even if Drupal does not have "inline" label for fieldset as of https://getbootstrap.com/docs/5.2/forms/layout/#horizontal-form, I will try to support that.

Finally, I removed the core library as its target details and summary and details.html.twig no more output those tags.

I was not able to call the accordion and accordion_item patterns because of the title and content fields. Not possible to prepare HTML to inject to those fields, it is otherwise escaped.

If someone has a tip on that, I will be happy that it is shared.

Fixing default open state.

Tested on my project with Drupal Commerce.

I need to test with forms in Layout Builder (offanvas)

That's what I thought. It breaks Layout Builder offcanvas forms.

When using gin_lb it is ok because gin_lb provides template suggestions so the presenter template are not taken into account.

I will check if possible to do something similar by default.

Commerce user registration step is no more styled.

The problem is that the fieldset of this form needs to be wrapped in a div that will take the col-md-6 class and no more the fieldsets directly.
