dojo.dnd.autoScrollNodes ignoring overflow-y: scroll

[JMace]

Apologies if this has been raised elsewhere.

I have a dojo dnd Source inside a scrolling div. When I drag a dnd item and attempt to have the div scroll automatically by dragging to the top or bottom of the scrollable div, it doesn't do anything. The overflow-y property is set to scroll. When I change the property to auto, it functions correctly.

I am using 1.3 but have tested on 1.5 and it appears not to be working there either.

I've knocked up some html to demonstrate it. By changing the overflow-y property between scroll and auto, you can see the problem.

I checked the source and it appears that the problem is in dojo.dnd.autoscroll.js on line 64. There is a call

var s = dojo.getComputedStyle(n);

then on the following line, a check for s.overflow. s.overflow should be scroll, but it's null, and so the div is being ignored.

There is an error in IE 9 when item dragged the scrollTop is set to zero.
