[FF] Cannot delete text at the end of the line with cursor placed after the space

[Anna Tomanek]

Reported on the forum: ​http://ckeditor.com/forums/CKEditor/Delete-key-not-working-if-at-end-of-line-past-a-space

Steps to reproduce:

1. Open the ​standard sample.
2. Place cursor at the end of the line (but not end of paragraph), after the trailing space.
3. Use Del to delete text.

Expected result: text from the next line is deleted.

Actual result: nothing happens.

Placing the cursor before the space works as expected and the text is deleted.

IE, Chrome do not seem to be affected. In Opera it seems like there is no space at the end of the line - the cursor always appears after the last character and deletion works as expected.

Problem can be reproduced from CKEditor 4.0 and only in new Firefox (FF 3.6 is free of this bug).

Put cursor here and press delete
