Steps to reproduce:

Place a 'draggable' element on page
Attach listener on 'dragstart' event for this element
Use setDrawImage method of dataTransfer object
Provide same element which has box-shadow applied to it via css
Use horizontal and vertical offset


Actual results:

Cursor offset is affected by usage of box-shadow. You can see in attached file how offset is set to (0,0) but cursor is not correctly positioned within drawn image.


Expected results:

Cursor placement should not be affected by usage of box-shadow. Correct result is seen when shadow is removed in css.
