At #dom-window-screenx & #dom-window-screeny says: > The screenX attribute must return the x-coordinate, relative to the origin of the screen of the output device, of the !!!top!!! of the client window as number of pixels, or zero if there is no such thing. > The screenY attribute must return the y-coordinate, relative to the origin of the screen of the output device, of the !!!left!!! of the client window as number of pixels, or zero if there is no such thing. I think the words "top" and "left" should be exchanged.
reassign to myself; apparently i am not the default assignee for this component
This appears to have been fixed at some point.
