tk2dUIItem events don't fire if Raycast Type == Physics2D in Tk 2d UICamera

[RyuK]

Hi, I followed the tutorial
http://www.unikronsoftware.com/2dtoolkit/docs/latest/ui/getting_started.html
and tried these events with my script
http://www.unikronsoftware.com/2dtoolkit/docs/latest/ui/system.html
but when I change Raycast Type == Physics2D in Tk 2d UICamera, events are not fired (Physics3D is fine).
Is it by design or is there any workaround for this?

The built in components use 3D physics. 2D physics is only supported if you want to build your own gui components with the built in scripts.
