HLayout.setLayoutAlign(Alignment.RIGHT) is placing members on the left?

IE8

For some reason this code

        HLayout rightControlPanel = new HLayout();
        rightControlPanel.setLayoutAlign(Alignment.RIGHT);
        rightControlPanel.setHeight100();
        rightControlPanel.setWidth("20%");
        rightControlPanel.setPadding(0);
        rightControlPanel.setMembersMargin(7);
        rightControlPanel.setBackgroundColor("pink");

        Menu reportMenu = new Menu();
        MenuButton reportButton = new MenuButton("Reports", reportMenu);
        //reportButton.setLayoutAlign(Alignment.RIGHT);
        rightControlPanel.addMember(reportButton);

places it's 1 member on the left top side of the HLayout? When I uncomment out the 2nd to last line, the member is still aligned on the left only this time it vertically aligns on the bottom?

I seem to be using the wrong API call, it works when I do

rightControlPanel.setAlign(Alignment.RIGHT);
