    Description

      Steps to reproduce

      1. Login as Admin and enable Realtime editing from Administration
      2. Go to a page
      3. Click "Comment" button
      4. Observe the JS console logs
      5. Add a comment
      6. Add a second comment
      7. Observe the JS console logs

      Expected results

      Not errors are displayed. The comments are added without any issues.

      Actual results

      On Step 4, after clicking the "Comment" button, a JS error is displayed;

      wysiwygEditor.js:65  Uncaught TypeError: Cannot read properties of undefined (reading 'channels')
    at new z (wysiwygEditor.js:65:39)
    at plugin.js:315:30
    at Object.execCb (require.min.js?r=1:5:16727)
    at e.check (require.min.js?r=1:5:10499)
    at e.<anonymous> (require.min.js?r=1:5:12915)
    at require.min.js?r=1:5:1542
    at require.min.js?r=1:5:13376
    at each (require.min.js?r=1:5:1020)
    at e.emit (require.min.js?r=1:5:13344)
    at e.check (require.min.js?r=1:5:11058)

      Then, after adding a comment, the following one is not added. A red error box is displayed on the browser below footer each time the "Add comment" button is clicked:

      The content cannot be saved because of a CKEditor internal error. You should try to copy your important changes and reload the editor.

      And some errors displayed in JS console:

      The same issue reproduces when adding annotations.

      As the full stacktraces could not be copied directly from JS console, please find attached the saved logs for each error.

      The issue reproduces also on XWiki 15.10.11, 16.4.1 and 16.5.0.
