Can modify markup outside of editor

[JoelValet]

Describe the bug
It seems that you can edit markup on the parent page that suneditor in embedded in

To Reproduce
Steps to reproduce the behavior:

1. Go to http://suneditor.com/sample/index.html
2. Highlight part of the "SunEditor distributed under the MIT license." string in the footer
3. In the editor go to "font color" and choose a color
4. It'll change the color outside the editor

Expected behavior
I would not expect the editor to be able to modify the markup outside of it
