All I can come up with is to try 1.1.1 beta.
Hmm, I'm not a coder.
I don't see it here: https://raw.githubusercontent.com/modxcms/evolution/1.1/install/changelog.txt
Or here: https://github.com/modxcms/evolution/tree/develop/assets/plugins/tinymce
Sorry probably can't help

Looking at Chromes inspect tool I found "which_editor" to be the name of the input for "Editor to Use". Searching for this in files throughout modx brough up some result which may be relevant. Give it a try it may yield the answer you are looking for.
