Floating Style doesn't respect background

[Mick]

I'm trying to set a custom background on a chart that uses the floating style:

Using the blinds (or other) style, this is easy:

Window w1 = new Window { Width = 640, Height = 480, Content = new Chart { Gallery = Gallery.Pie, Style = Blinds.Style, Background = Brushes.Red } };w1.Show();

However, when I use the "Floating" Style, the background never show up:

Window w2 = new Window { Width = 640, Height = 480, Content = new Chart { Gallery = Gallery.Pie, Style = Floating.Style, Background = Brushes.Red } };w2.Show();

How do I get the floating style to respect the background that I set?

We fixed this in build 3966. Starting on that build we changed the palette used in Floating so that it forces the background to be transparent but honor the background set by the user.
