If the focus ring were to be drawn around the element that currently has focus, then the entire focus ring would be drawn outside of the visible region.

Even if you don't make it full size, if the focus ring is drawn into the canvas buffer, you don't know how much room you need to account for. (If the focused control is near the edge of the canvas.)
