ProgressIndicator rendering with firefox (linux, windows)

What steps will reproduce the problem?

1.Create a panel which enables ProgressIndicator:

/*
** MobileLoadingPanel.java
*/
public class MobileLoadingPanel extends Composite {

    private static MobileLoadingPanelUiBinder uiBinder = GWT.create(MobileLoadingPanelUiBinder.class);

    interface MobileLoadingPanelUiBinder extends UiBinder<Widget, MobileLoadingPanel> {
    }

    public MobileLoadingPanel() {
        initWidget(uiBinder.createAndBindUi(this));
    }
}

/*
** MobileLoadingPanel.ui.xml
*/
<!DOCTYPE ui:UiBinder SYSTEM "http://dl.google.com/gwt/DTD/xhtml.ent">
<ui:UiBinder xmlns:ui="urn:ui:com.google.gwt.uibinder"
         xmlns:g="urn:import:com.google.gwt.user.client.ui"
             xmlns:m="urn:import:com.googlecode.mgwt.ui.client.widget">

    <ui:style>
        .indicator {
            margin: auto;
            margin-top: 50px;
        }

        .text {
            text-align: center;
            margin-top: 20px;
        }
    </ui:style>

    <m:LayoutPanel>
        <m:ProgressIndicator addStyleNames="{style.indicator}" />
        <g:HTML addStyleNames="{style.text}">
            <ui:text from="{msg.loadingMessage}" />
        </g:HTML>
    </m:LayoutPanel>
</ui:UiBinder>

What is the expected output? What do you see instead?
