IE8 - Cursor Cannot Jump To End Of Last Smiley In CK Editor

When I insert data into ckeditor using emoticon, I want to edit the data again, but after adding the emoticon, I cannot click. Can't put text in ckeditor for ie8 after emoticon. If I want to save the text or emoticon after that, the mouse cursor will not move to the end of the emoticon. But if I were to use the final keyboard button then the mouse cursor appears after the emoji. This is an IE 8 only issue.
