Thank you for reporting the issue to us. We have checked and everything works as expected on our demo – have a look at the video demonstration. Could you please provide us with some additional steps to reproduce the issue?
I’m using a more updated version than the demo on your site, which we implemented on our app: http://jsfiddle.net/f243r8r5/9/
Please check there.
Thank you for sharing the sample with us. It helped us to reproduce the issue on our side. The fix will be ready in the minor release 2.314 (ETA Apr 24).
