I'm using the Editor and the Immutables functionality.
When I'm editing a document in the Editor that contains Immutables in Internet Explorer and I 'Undo' (Ctrl + Z) something the formatting of the immutable content is messed up or disappears completely.This works fine in Chrome but not in Internet Explorer.
If you want to test use this Kendo demo in Internet Explorer
Now select some text in the example and Bold it using the editor bold command. Now undo (Ctrl + z). The Immutable fields disappear!!
Any help appreciated Telerik
