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:
ckeditor.js:458 Uncaught TypeError: Cannot read properties of undefined (reading 'getSelection') at CKEDITOR.dom.selection.getNative (ckeditor.js:458:125) at new CKEDITOR.dom.selection (ckeditor.js:456:179) at CKEDITOR.editor.getSelection (ckeditor.js:453:347) at e.<anonymous> (plugin.js:270:28) at e.l (ckeditor.js:10:246) at e.<anonymous> (ckeditor.js:12:91) at window.CKEDITOR.window.CKEDITOR.dom.CKEDITOR.editor.CKEDITOR.editor.fire (ckeditor.js:13:285) at e.getData (ckeditor.js:275:166) at e.k (ckeditor.js:1312:64) at e.l (ckeditor.js:10:246)

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.
