Content copied from MS Word isn't properly formatted after publishing.
Steps to reproduce:
1. Prepare some chunk of text in MS Word and insert new lines (Shift+Enter) in between e.g. "one line text [Shift+Enter] another line of text ...".
2. Paste it in the RichText Editor.
3. Hit "Publish".
4. Visit published content in the admin panel.
All the newlines are gone and the text is visible in one line.
