When adding additional config i get a JS code but it does work

When i have additional config like:

fos_ck_editor:
  default_config: my_config
  configs:
    my_config:
      language: nl
      extraPlugins:
        - 'autogrow'
        - 'youtube'
        - 'wordcount'
      autoGrow_minHeight: 500
      autoGrow_maxHeight: 500
      autoGrow_onStartup: true

I get the following JS error when rendering the template:

VM1727 ckeditor.js:19 [CKEDITOR] Error code: editor-element-conflict. {editorName: 'x'}

VM1727 ckeditor.js:19 [CKEDITOR] For more information about this error go to https://ckeditor.com/docs/ckeditor4/latest/guide/dev_errors.html#editor-element-conflict

But the editor renders correctly.

When i enabled jQuery it worked i got the suggestion by looking at second answer https://stackoverflow.com/questions/59158795/ckeditor-error-code-editor-element-conflict
