Ah, yeah, as specced the model totally ignores Mac-like drag cancelation
effects.

That shouldn't be hard to fix. Basically, whenever the "current drag operation"
is "none" after the "dragend" event, the drag should be considered to be
canceled. (Thus to cancel a drag in a 'drop' event you just need to set
event.dataTransfer.dropEffect to "none".)
