Floated windows have a transparent background

[VlcekM]

How to reproduce:

1. Clone any of the provided examples (e.g. "DockXamlSample")
2. Start the app
3. Float any of the docked windows

You must have not copied some styles from original App.axaml, does this happen to DockXamlSample also ?

[VlcekM]

Indeed, it happens on all 3 samples.

I think this happening because the RegionColor is being set to Transparent

Dock/samples/DockXamlSample/App.axaml

Line 9 in 30293a3

<Color x:Key="RegionColor">Transparent</Color>

I've fixed it with

HostWindowLocator =
        new Dictionary<string, Func<IHostWindow?>> {
            [nameof(IDockWindow)] = () => new HostWindow {
                Background = GetThemeColor("DockToolHostWindowBackground")
            }
        };

in DockFactory.InitLayout
