Django, django-ckeditor, Google MDL: Cannot read property 'getSelection' of undefined

Question

I am using Django 1.11 and django-ckeditor for text fields in admin panel, and also for some inputs outside the admin (in public forms). As a CSS framework - Google material design lite.

When I trying to integrate ckeditor to public forms, charfield with ckeditor does not working at all. Something like I can't focus to this field, and when I click to any of ckeditor control elements I get errors

Uncaught TypeError: Cannot read property 'getSelection' of undefined

    at CKEDITOR.dom.selection (ckeditor.js:443)

And in Firefox:

Forms.py:

from ckeditor_uploader.widgets import CKEditorUploadingWidget


class PaymentForm(forms.Form):
    comments = forms.CharField(widget=CKEditorUploadingWidget())

To integrate ckeditor js scripts I'm using {{ form.media }} in template.

First of all I tried to search info about this errors and any know fixes, but any of founded doesn't worked for me. Also I found some similar questions with ckeditor here, but without any working solution.

When I checked all js scripts, I found that problem in Javascript of Google material design lite css framework https://github.com/google/material-design-lite

When material.min.js are integrated to page scripts - ckeditor does not work. Not minified framework js: https://code.getmdl.io/1.3.0/material.js

PS: This is my first question ever made here, sorry for any inconvenience.

Thanks for any help!

Made some changes to make django-ckeditor work with google material design lite framework. If needed, you can use this version of django-ckeditor (my fork): https://github.com/wardal/django-ckeditor while we waiting official answer and solutions here: https://github.com/django-ckeditor/django-ckeditor/issues/429
