16391	CKEditor: Clipboard is pasted multiple times	Fg195		"In Firefox Version Firefox 49.0.1:

When a text is pasted from a word file or a Thunderbird e-mail the text is SOMETIMES pasted multiple times instead of just once. It's no issue with the clipboard since pasting it into notepad works just fine. Any hints on what might cause this issue are welcome. Thank you!

The issue is very similar to this one: ​https://dev.ckeditor.com/ticket/12995"	Bug	pending	Normal		General
