Problem/Motivation

I tried to switch over from using the "Limit allowed HTML tags and correct faulty HTML" to HTML Purifier, but I can't enable it for our "Advanced HTML". When I try to save the text format, i get an error:

The current CKEditor 5 build requires the following elements and attributes:
<br> <p> <h2> <h3> <h4> <strong> <em> <s> <blockquote> <a href class id target="_blank"> <ul> <ol reversed start> <li> <img src alt height width data-entity-type data-entity-uuid>
The following elements are missing:
<br> <p> <h2> <h3> <h4> <strong> <em> <s> <blockquote> <a href class id target="_blank"> <ul> <ol reversed start> <li> <img src alt height width data-entity-type data-entity-uuid>

I've attempted to add my own configuration to this filter, changing the "Allowed:" value from "null" (default) to:
Allowed: br,p,h2,h3,h4,strong,em,s,blockquote,a[href|class|id|target],ul,ol[reversed|start],li,img[src|alt|height|width|data-entity-type|data-entity-uuid] but this doesn't doesn't get rid of the error.

Steps to reproduce

  1. Install D9 using the standard installation profile
  2. Install/Enable the HTML Purifier module
  3. Visit the Basic HTML text format configuration page: /admin/config/content/formats/manage/basic_html
  4. Disable the filter "Limit allowed HTML tags and correct faulty HTML"
  5. Enable the HTML Purifier filter
  6. Save the text format, and see a very similar error as posted above.
