dojo/dnd/Source receive wrong 'onDraggingOut()' 'onDraggingOver()' function calls

[ManuAir]

I experienced a strange problem with dojo/dnd when I'm dragging an element inside a <div> handled by the Source class.

if I swipe the mouse from left to right, the Source class receive only one onDraggingOut() call (even if the mouse is really inside the div)

if I swipe from right to left, the Source receive multiple calls of the methods onDraggingOver() and onDraggingOut() something like every one/two pixels of movement.

if I swipe from right to left only by one pixel, the Source receive a single onDraggingOver() call, and after a short time, like 0.8 seconds, it receive a onDraggingOut() call.

I experienced this problem only with Chrome, Firefox and IE seems to be not affected.

After some debugging I think that, Firefox and IE are not affected because in this browser the lines of code from row 37 to row 51 in the file dojo/touch.js, are not executed. In IE because there is a special handling, and in FF because has("touch") returns false (incorrectly)
