Thank you very much for the shared fiddle.
It seems like this problem only occurs, when the editor is initialized in inline editing mode. You can also observe this behaviour in our demo for inline editing. Sorry I missed that when I first answered your question.
I have logged this issue in our internal bug tracker, so it will be fixed in a later build. As a small gesture of gratitude I have updated your Telerik Points balance.
Thank you very much for your understanding on this matter.
