Disabling TimeScale causes dragged appointments to display "Undefined - Undefined"

I have a Schedule where I want to disable TimeScale for my "week" and "work week" views.
.TimeScale(x => x.Enable(false))

However, whenever I do so, I will get the text "Undefined - Undefined" when I drag appointments to a new resource.
  • If I slowly drag the appointment to a new ressource, the appointment displays the proper text
  • If I quickly (regular mouse speed) move the dragged appointment back and forth between resources it changes the text to "Undefined - Undefined"

Am I using the feature wrong or is this a bug?
I have attached an example project where the issue can be seen.

I found another issue with dragging appointments when TimeScale is disabled.
If I drag an appointment to the left-most part of the Schedule, it will be dropped on the day before the actual day.

In the previously linked sample I have the following function:

    function OnDragStop(args)
        console.debug("appointment.StartTime: " + args.appointment.StartTime);
        console.debug("draggedAppointment.StartTime: " + args.draggedAppointment.StartTime);
        args.cancel = true;

This following is the output when I drag an appointment from Nov. 9th to Nov. 8th (left-most day in the Schedule):
appointment.StartTime: Sat Nov 07 2015 08:00:00 GMT+0100 (Rom, normaltid)
draggedAppointment.StartTime: Mon Nov 09 2015 08:00:00 GMT+0100 (Rom, normaltid)

Hi, I just want to follow up on this issue. 
The issue was scheduled for Sep. release but is now listed as scheduled for Oct. release. 
Is it possible to get a more precise estimate of when we can expect this issue to be resolved?

Kind regards, Toke Wivelsted.
