Hello,
We are not aware of such an issue, however, there is a there is a chance to have a problem with the mentioned version. I have identified a suspicious code, but I cannot be completely sure without a sample project which demonstrates the issue. May I ask you to isolate the problem in a sample project and send it to me? I will debug it on my side and will try to fix the problem.
Your kind assistance will be greatly appreciated.

While i try to create a sample project, you can do the scenario by placing Thread.Sleep(500) in the set of the Selected item, this will reproduce this issue.

Hello,
Were you able to reproduce the problem in the sample project which was attached to my previous reply? Because I was not able to.
If you are able to reproduce it, may I ask you to modify my sample project and return it back to me?
