ENTER_BR mode removes trailing <br>

[Matthew Leffler]

Steps:

1. View nightly ​http://nightly.ckeditor.com/13-02-27-14-12/full/samples/plugins/enterkey/enterkey.html
2. Set config.enterMode = CKEDITOR.ENTER_BR; config.shiftEnterMode = CKEDITOR.ENTER_P; equivalents using select boxes.
3. In source mode enter <br />
4. Switch to wysiwyg and back to source.

Expected result: The <br /> should still be the source.

Actual result: The source is blank.

Notes: I can reproduce this in every browser I've tried from CKEditor 4.0 through nightly.

@mattleff I have just described this ticket :)

If you don't mind I will close this one as DUP and leave mine open as I think mine is described just a little bit better. Not that I have anything against this description – it also explains what is wrong. Mine ticket on the other hand targets start version, excludes 3.x branch right in description.

DUP of #10146

@j.swiderski That's fine by me, particularly if it gets fixed. ;)
