Bug? Modal Window & Split Panel

Hello again everyone,
I am back after being away for quite a while -_-

There seems to be a problem with SplitPanel when put in a modal window.
If you try to move the split bar, the window freezes and you have to refresh the page to have it working again.
I have to add that everything is fine with a modeless window.

Here is the code I use to reproduce this issue:

final Window mainWindow = new Window("Test for split panel in a modal window");
		setMainWindow(mainWindow);
		
		VerticalLayout vl = new VerticalLayout();
		final Window modalWindow = new Window("Modeless Window", vl);
		vl.setWidth(200, Sizeable.UNITS_PIXELS);
		vl.setHeight(200, Sizeable.UNITS_PIXELS);
		modalWindow.setModal(true); // This line causes the problem
		mainWindow.addWindow(modalWindow);
		
		SplitPanel splitPanel = new SplitPanel(SplitPanel.ORIENTATION_HORIZONTAL);
		splitPanel.setSplitPosition(20);
		vl.addComponent(splitPanel);

		VerticalLayout leftLayout = new VerticalLayout();
		splitPanel.setFirstComponent(leftLayout);
		VerticalLayout rightLayout = new VerticalLayout();
		rightLayout.addComponent(new Label ("Sample Label"));
		splitPanel.setSecondComponent(rightLayout);

Thanks,
Houman

Seems like a bug. I created http://dev.vaadin.com/ticket/4067 for it.

EDIT: Fixed it, try the next nightly build.
