[BUG] - Content Component as Angular element - produces the error - properties of undefined (reading 'data-ck-expando')

[Dinesh]

Environment

Angular version - 15.2.0

• Hosting type
  • [] Form.io
  • [X ] Local deployment
    • Version:
• Formio.js version:

    "@formio/angular": "^5.5.0-rc.11",
    "@formio/js": "^5.0.0-rc.27",

• Frontend framework:
• Browser: Chrome
• Browser version: latest

Steps to Reproduce

1. Create an angular element - with formio.
2. Build the project to generate the javascript and css file and include it in a HTML file.
3. open HTML file and try to add content component to the form. Due to the ckeditor the following error occurs. (see video more details.)

sfs-form-designer-element.js:1 Uncaught TypeError: Cannot read properties of undefined (reading 'data-ck-expando')
    at dr (emittermixin.js:256:9)
    at Eu._getProxyEmitter (emittermixin.js:112:39)
    at Eu.stopListening (emittermixin.js:86:23)
    at Eu.destroy (view.js:492:8)
    at viewcollection.js:89:26
    at Array.map (<anonymous>)
    at dl.map (collection.js:334:22)
    at dl.destroy (viewcollection.js:89:8)
    at dl.detachFromDom (bodycollection.js:94:9)
    at Gl.destroy (editoruiview.js:52:13)

Note the above error occurs only if you export formio as an Angular Element. Regular angular projects work fine.

Expected behavior

Content component should work as expected.
