OnPaint draws a border so it's necessary to fix crbug.com/719414

   views::Painter::PaintFocusPainter(this, canvas, focus_painter_.get());
 }
 
 void MessageView::OnFocus() {
+  views::View::OnFocus();

OnFocus fires an a11y event so I think it's needed.

   // We paint a focus indicator.
   SchedulePaint();
 }
 
 void MessageView::OnBlur() {
+  views::View::OnBlur();

Actually View::OnBlur() is empty but I added this for consistency with OnFocus.

   // We paint a focus indicator.
   SchedulePaint();
 }
