I'd like to disallow all HTML and only allow plain text in comments across the site for all users, authenticated or not, but I still want to use other HTML filters for other content types. How can I achieve that in Drupal 8?
I've created a custom text format called "No HTML" and set it as the default format for comment bodies at
admin/structure/comment/manage/comment/fields/comment.comment.comment_body. But instead of disallowing all HTML, it gives the option to change the text format to any other format available to the user.
How can I get comments to only use my "No HTML" text format for all users without disabling the other text formats for other content types?
