Communities forum and calendar event post ckeditor paste from word issue

For AEM 6.5.10 Communities, we are seeing that when attempting to paste from word file, an error is thrown as below

Error in granite.js

when checked this path "/libs/clientlibs/ckeditor/resources/ckeditor/plugins/pastetools/filter/common.js", it seems that "pastetools" folder is not there for current AEM 65 version we are on.

This looks like was something that was available for older ckeditor version and now there is a "pastefromword" folder which is probably not referred from the granite.js

Is this a bug? 

Alternatively, even including the desired ckeditor version from custom clientlibs might not help since some OOTB code (last point granite.js) is trying to get to "pastetools" folder and getting a 404..

Anyone faced this issue?
