Thank you for the detailed information.
I tried to reproduce the behavior you describe, but with no luck - please see the attached video.
When testing your code, the 2016.2.613 version of our controls was used, could you please specify what is the version of our assemblies in the application where the error appears?
In case it's an older version, it would be helpful if you could try to reproduce the error with the latest version and let us know the result.
Looking forward to your reply.
