Conflict with other autocomplete ckeditor plugins

Problem

The Linkit plugin conflicts with other ckeditor plugins using autocomplete. I encountered this while coding my own custom plugin.

Steps to reproduce

1. Download for example the module "CKEditor Entity Link" (it uses an autocomplete field) : https://www.drupal.org/project/ckeditor_entity_link →
2. Add the plugin to your ckeditor toolbar
3. Edit a rte field in a node :
   • add a link using the Linkit plugin
   • add a link using the CKEditor Entity Link plugin

And we get :

More precisely it happens on this part :

$autocomplete.autocomplete(autocomplete.options).each(function () {
          $(this).data('ui-autocomplete')._renderItem = autocomplete.options.renderItem;
        });

Somehow there's still some linkit html attributes in the .ui-autocomplete result list.

If anyone has a idea :)
