Focus issue after inserting table

[Damian]

When inserting a table at the end of a document it is not possible to navigate past the table to continue entering text.

Steps to reproduce:

1. Open nightly build. Currently (​http://nightly.ckeditor.com/3105/_samples/replacebyclass.html)
   
2. Add new line to the existing text in the editor
   
3. Add new table with all default values
   

Expected behavior:
Table is added at the carat position. It is possible to position the carat directly after the table to continue adding text.

Actual behavior:
The table is added as expected. It is not possible to position the carat after the table, making it difficult to continue entering text into the document without having to go into source mode.

Works for me in IE.
