endPoints of JsPlumb are not updating within container with scroll overflow when dragging them

I have two draggable layers and there is a connection between them which is based on JsPlumb library. Working example is available here. The picture is here:

When these layers are located in the body there is no any problems, but when I put them inside another layer (i.e. container) with overflow: auto OR scroll; the problem starts to show itself. When you move a layer o开发者_如何学Goutside the visible area of the container the endpoints of the draggable layers don't move with a draggable layer but instead they (endpoints) stop in the border of the container.

The author of the JsPlumb library had solved this problem for a JsPlumb 1.2.x version here, but UNFORTUNATELY this script doesn't work anymore for JsPlumb 1.3.x. Does anybody know how this problem could be solved? I (and think many developers) really need to solve this problem (if it hadn't been solved yet, because I had googled and didn't find anything useful).

Thanks to the author of jsPlumb library I was able to solve the problem. He has released a new RC version of the library for the appeared problem and now the problem is gone! Working example is is available here.
