IE: using Undo after Unlink moving cursor to start of document in editor

[satya]

To reproduce the defect:

1. Type some paragraphs of text and insert a link using link dialog.

2. Keep cursor inside the link and click on Unlink icon or open context menu menu and click on Unlink option.

3. Link inserted in step 1 is removed and cursor stays at the same paragraph where we have the link before.

4. Press Undo icon in the Tool bar or use Ctrl + Z

Expected Result: Link that was removed comes back and cursor stays inside the link.

Actual Result: Link that was removed comes back but cursor moves to start of document in editor body.

This will be huge inconvenience to the user if document has large number of paragraphs.
