793495 - dragleave event fired after dragend and without a previous dragenter

Status: UNCONFIRMED

(Core :: DOM: Copy & Paste and Drag & Drop, defect, P5)

User Agent: Mozilla/5.0 (X11; Linux i686; rv:10.0.1) Gecko/20100101 Firefox/10.0.1

Steps to reproduce:

I have a series of possible drop zone elements in a block container.

1. Drag an element A over another element B.
2. Drop A on B.
3. Element A is inserted after element B in the block (so it is moved from the drag position to the drop position and element B is shifted away from its original position as the block shuffles its children)


Actual results:

1. dragenter event is fired when dragging over element B
2. drop event is fired on element B and dragend event on element A
3. dragleave event is fired on element A


Expected results:

Certainly No dragleave event on element A.  Nothing is ever dragged over element A and no dragenter or dragover events are ever generated for it.

Probably no dragleave event on element B either, according to the spec, although I'm not sure what the exact behaviour should be when the drop element is shifted out from under the mouse by the drop taking place.
