I was not able to reproduce this behavior on my side. Could you please provide more information about the issue that you experience : maybe special sequence of reproduction steps, your browser version? Also, do you reproduce that behavior on our First Look
online demo? It will be best, if you open a new support ticket and send us some screenshots of that behavior. Once we reproduce the issue, then we will be able to provide a solution for you.
We are looking forward to hearing from you,
the Telerik team
