Sorry for the confusion, I thought that you are using a third-party or a custom DiffEngine instead of the built-in, which is actually obsolete.
The discontinued Track Changes dialog is replaced by the Track Changes functionality
. All functionality related to the old, non-supported dialog is still available due to legacy matters, but not support.
Also, by design the DiffEngine is seeking changes as text and attribute-related differences are not tracked.
On a side note, the used DiffEngine is not a Telerik product. It is a third party source, which can be found here - http://www.mathertel.de/Diff/
. I suggest following the provided site for further improvements and for using this functionality as a third-party solution.
Check out the Telerik Platform - the only platform that combines a rich set of UI tools with powerful cloud services to develop web, hybrid and native mobile apps.
