 void CanvasRenderingContext2D::drawFocusRing(const Path& path, Element* element)

Not new to this patch, but "element" seems to be unused in this function.

 {
     GraphicsContext* c = drawingContext();
     if (!c)
         return;
 
     c->save();
     c->setAlpha(1.0);
     c->clearShadow();
     c->setCompositeOperation(CompositeSourceOver, BlendModeNormal);
 
-    RefPtr<RenderStyle> style(RenderStyle::createDefaultStyle());
+    // These should match the style defined in html.css.
     Color focusRingColor = RenderTheme::focusRingColor();
-    c->drawFocusRing(path, style->outlineWidth(), style->outlineOffset(), focusRingColor);
+    const int focusRingWidth = 5;
+    const int focusRingOutline = 0;
+    c->drawFocusRing(path, focusRingWidth, focusRingOutline, focusRingColor);
     didDraw(path.boundingRect());
 
     c->restore();
 }
