[whatwg] Why does CanvasRenderingContext2D.drawImage not draw a video's poster?

The spec. for CanvasRenderingContext2D.drawImage says draw nothing when
a video element's readyState is  HAVE_NOTHING or HAVE_METADATA. I was
wondering why this was chosen vs. drawing the poster. A search in the
list archive didn't turn up any discussion or explanation.
