When editing a content in Firefox 49 and previous versions, text has no line break on CKEditor.

Steps to reproduce

1. Admin > Content > Web Content;
2. Click on 'Add' > 'Basic Web Content';
3. Enter a large word that is longer than the text editor width.

Expected behavior

There are line breaks in order to fit the text in view.

Current behavior

There is no line breaks and a horizontal scroll bar appears.

#10448 ([Bidi] Lack of scrollbar in the RTL text direction) – CKEditor can fix that behavior.

It won't be reproduced on ee-7.0.x and master because the fix already got into those branches with the most recent CKEditor versions.
