Hi Michael,
Thank you for reporting the case. It has been logged as a bug and will be fixed in the near future. I cannot say when the fixture will be introduced. You can follow the current thread and once there is a change in it, you will be notified. We cannot provide a workaround for this issue.
I've updated your Telerik points as a sign of gratitude.
Thank you once again for your report!
Regards,
Petar
