Hello sf,

Thank you for bringing this problem to our attention. We have already handled this issue and it will be fixed in the next internal build. Unfortunately, I am unable to provide stand-alone fix for it. Please excuse us for the temporal inconvenience.

As a small token of gratitude I have updated your Telerik points.

Best wishes,
Dobromir
