There are some workarounds in code, which prevent of throwing this error. Maybe there will be time to investigate what exactly happens here:

https://github.com/ckeditor/ckeditor4/blob/acf57ad52650fafc07df2e98886517e82fd585da/core/dom/domobject.js#L141-L147

https://github.com/ckeditor/ckeditor4/blob/acf57ad52650fafc07df2e98886517e82fd585da/core/editable.js#L544-L547

From a brief analysis, it looks like issue tends to appear when we accessing a property/value/etc. of native HTML element which is detached.

Expected result

no error or some better error handling/prevention

Actual result

simple try…catch which prevents error occurrence.

possible reason and solution made by jQuery https://github.com/jquery/sizzle/blob/5b3048605655285a81b06fbe4f49f2a14a8d790f/src/sizzle.js#L472-L480

The wysiwygarea uses iframe which probably causes a lot of reloads.
