When drag'n'droping an item over an iframe scrolled, the element dragged is misslocated.

Here is the problematic code (at line 146 of IFrame.js)



Code:



event.xy = [iframeXY[0] + eventXY[0], iframeXY[1] + eventXY[1]];

That I had to replace with:


Code:



event.xy = [iframeXY[0] + eventXY[0] - (iframeEl.dom.contentWindow.document.documentElement.scrollLeft || iframeEl.dom.contentWindow.document.body.scrollLeft),
iframeXY[1] + eventXY[1] - (iframeEl.dom.contentWindow.document.documentElement.scrollTop || iframeEl.dom.contentWindow.document.body.scrollTop)];

Can be reproduced on IE11 in mode IE10 ; Chrome 39 ; Firefox 35

Here a fiddle that is not working at all ; I don't know why : http://ift.tt/1AY417l

(I mean drag and droping over the iframe usualy works and not in my fiddle ;; and what is never working is to scroll down the iframe first)
