WPF RibbonWindow + Ribbon = Title outside screen?

Question

I\'m trying out Ribbon control in combination with RibbonWindow, however they fail even in trivial experiments.

This is not a solution, perhaps not even a work around, but rather a poorly hack, that I hope to only use for a short time until the problem is fixed in the framework.

Code is mainly copy+paste from this question https://stackoverflow.com/a/8082816/44726

I've changed the allowed screen position, which seems to help the problem, not fix it.

Call is like this in the code behind

        InitializeComponent();
        RibbonWindowService.FixMaximizedWindowTitle(this);

public static class RibbonWindowService
{
    public static void FixMaximizedWindowTitle(Window window)
    {
        window.SourceInitialized += WinSourceInitialized;
    }

    [DllImport("user32")]
    internal static extern bool GetMonitorInfo(IntPtr hMonitor, MONITORINFO lpmi);

    [DllImport("User32")]
    internal static extern IntPtr MonitorFromWindow(IntPtr handle, int flags);

    private static IntPtr WindowProc(IntPtr hwnd, int msg, IntPtr wParam, IntPtr lParam, ref bool handled)
    {
        switch (msg)
        {
            case 0x0024:
                WmGetMinMaxInfo(hwnd, lParam);
                handled = true;
                break;
        }

        return (IntPtr)0;
    }

    private static void WmGetMinMaxInfo(IntPtr hwnd, IntPtr lParam)
    {
        MINMAXINFO mmi = (MINMAXINFO)Marshal.PtrToStructure(lParam, typeof(MINMAXINFO));

        // Adjust the maximized size and position to fit the work area of the correct monitor
        int MONITOR_DEFAULTTONEAREST = 0x00000002;
        IntPtr monitor = MonitorFromWindow(hwnd, MONITOR_DEFAULTTONEAREST);

        if (monitor != IntPtr.Zero)
        {
            MONITORINFO monitorInfo = new MONITORINFO();
            GetMonitorInfo(monitor, monitorInfo);
            RECT rcWorkArea = monitorInfo.rcWork;
            RECT rcMonitorArea = monitorInfo.rcMonitor;

            // Offset top and left 1 pixel improves the situation
            rcMonitorArea.top += 1;
            rcMonitorArea.left += 1;

            mmi.ptMaxPosition.x = Math.Abs(rcWorkArea.left - rcMonitorArea.left);
            mmi.ptMaxPosition.y = Math.Abs(rcWorkArea.top - rcMonitorArea.top);

    }
