Simon Urli so your problem was only with the standalone WYSIWYG editor? If so, then you could use what's indicated on https://extensions.xwiki.org/xwiki/bin/view/Extension/CKEditor+Integration#HExecuteJavaScriptcodeinsidetheeditingarea28XWiki10.102B29 , i.e. pass:
{'wysiwyg': true}
when loading the JSX.
And yes, we need to remove this option (was introduced before the in-place edit mode).
