You've transformed the shape outside of its own canvas. Although the Transform will preserve the Domain of Definition (DoD) such that pixels outside the canvas still exist, the Shadow node doesn't have that ability. From the Shadow's perspective, the portion of the Clover outside its original dimensions doesn't exist. Put in a Crop right after the Transform and set it to the same dimensions as your Background in order to expand the canvas.
