I have just answered to the support ticket you have sent on this matter. Here is my answer for community reference:
"I have tested the described scenario at my end, but I was unable to replicate the described issue. Here is a video
demonstrating the RadComboBox's behavior at my end, with the specified version applied."
In addition, I would like to ask you to keep the conversation in the other thread (Ticket ID - 608036), in order to have a consistent correspondence.
