Key navigation works inproperly on timepicker

open that sample: DHTMLX - Basic Widget
then open timepicker from calendar, click on hour’s value and press right arrow - everything works well here.

Now compare it with that sample when timepicker is attached to form: DHTMLX - Basic Widget
do the same: open timecontrol, click on hour’s value and pres right arrow - focusing was moved from input to popup and that is bugged.

I apologize for the delay with the reply.
