I used the code which Charles posted to build a sample project. But unfortunately I couldn't reproduce the issues you are both experiencing. Attached I am sending you a short video for reference.
Please check it out and if I am doing something different than you, provide us with step-by-step description on how to reproduce the issues.
Also, sending us a sample running project, which we can test here locally, in which we can observe the problems, will help us resolve the issues in a timely manner.
Looking forward to your replies.
All the best,
the Telerik team
