Description
When a Window is created and then moved down and to the right it experiences an abnormal resize. The window itself is taller and narrower but it's shadow remains the original size. Resizing seems to fix it up.

Run mode
Both dev mode and production

Steps to reproduce the problem
Create a Window with a single '<p>' paragraph and then move it. See code below.

Test case

    
public class Entry implements EntryPoint {
        @Override
        public void onModuleLoad() {
            Viewport v = new Viewport();
            v.setWidget(new LaunchPanel());
            RootLayoutPanel.get().add(v);
        }
    }

    public class LaunchPanel implements IsWidget {
        private final Widget w;

        public LaunchPanel() {
            TextButton b = new TextButton("Open Window");
            b.addClickHandler(new ClickHandler() {
                @Override
                public void onClick(ClickEvent event) {
                    Window w = new Window();
                    w.setHeadingHtml("A Window");
                    w.add(new HTMLPanel("<p>Move this window down and to the right.<br/>" +
                            "You should see an abnormal resize with the shadow remaining the original size.<br/>" +
                            "Resizing it fixes it up again.</p>"));
                    w.setMinHeight(10);
                    w.setMinWidth(20);
                    w.setOnEsc(true);
                    w.show();

                }
            });
            w = new SimplePanel(b);
        }

        @Override
        public Widget asWidget() {
            return w;
        }
    }
