Panel Overlay over WindowsFormsHost

I have a SWF object embedded in a WindowsFormsHost control inside a WPF window.

I want to add a toolbar to a swf movie.

The problem with the code snippet that I have below is that when a new child is added to the host control (or the movie is loading, I have not figured out what else), the toolbar becomes invisible. It seems that the z-index swf is for some reason set to the top.

Here's what it looks like:

XAML:

<Grid Name="Player">
   <WindowsFormsHost Name="host" Panel.ZIndex="0" />
   <Grid Name="toolbar" Panel.ZIndex="1" Height="50"
      VerticalAlignment="Bottom">
           [play, pause, seek columns go here]
   </Grid>
</Grid>

WITH#:

private void Window_Loaded(object sender, RoutedEventArgs e)
{
   flash = new AxShockwaveFlashObjects.AxShockwaveFlash();
   host.Child = flash;
   flash.LoadMovie(0, [movie]); // Movie plays, but no toolbar :(
}

Any understanding of this problem would be greatly appreciated.

Update: . Since no suitable answer has been posted, I posted my own solution below. I understand that this is more of a hack than a solution, so I am open to other suggestions.
