SpinnerItem icons in wrong place

[hopey_dishwasher]

Hello. Using GWT 2.2.0, smartgwt pro 2.5.

When I call setIcons on a spinnerItem, it puts the icon below the spinner buttons, rather than to the right of them as I would expect.

How do I get the icon to go to the right of the spinner item, like they do for other FormItems?

Sample code used to create the attached screenshot:

    	FormItemIcon tick = new FormItemIcon(){{
    		setSrc("[SKIN]/actions/approve.png");
    	}};

    	final SpinnerItem testSpinner = new SpinnerItem("spinner", "Hello!");
    	testSpinner.setIcons(tick);
    	
    	final TextItem testText = new TextItem("text", "Hello!");
    	testText.setIcons(tick);
    	
    	new DynamicForm() {{
    		setFields(testSpinner, testText);
    	}}.draw();

Thanks

On closer inspection I find that this happens in Chrome(ium), but not in firefox.
