Text format restricted_html uses editor

How do we reproduce this ? Standard install doesn't even have an editor on the restricted format ..

I'm sorry, but none of this makes any sense.

Though the editor is disabled with restricted_html, it is activated on the edit form.

This is untrue. I created an article with the restricted_html text format, saved it, then edited it and still no text editor.

If I create my own text format similar to restricted_html, it works.

What works?

The reason seems to be that "editor" is still a requirement for this text format, but it is deactivated as you can see in the configuration:

This is not what the restricted_html text format config entity looks like by default. It looks like this:

uuid: aee4916f-2bbc-4759-9300-0e7092ce5f80
langcode: en
status: true

      filter_html_help: true
      filter_html_nofollow: false
  filter_autop:
    id: filter_autop

  filter_url:
    id: filter_url
    provider: filter
    status: true
    weight: 0
    settings:
      filter_url_length: 72

No dependency on the editor module.

Thus the input is polluted with p-tags!

Huh? Yes, of course, that's how it is configured: to automatically create <p>-tags, and not rely on the text editor to create them. If you associate a text editor with the restricted_html text format, you must manually remove the filter that automatically creates <p> tags.
