Binding failure when using AvalonDock.Themes.VS2013

[josdemmers]

Using VS2022, .NET6

A project with AvalonDock.Themes.VS2013 shows a binding failure. The theme however is looking fine. So not that big of an issue.

Binding failure: Severity: Error Data Context: null Binding Path: Fill Target: GeometryDrawing.Brush Target Type: Brush Description: Cannot find governing FrameworkElement or FrameworkContentElement for target element.

The issue is caused in ./Themes/Generic.xaml by the <Rectangle.Fill> in the following styles:

<Style TargetType="avalonDockControls:AnchorablePaneTitle">
<Style x:Key="{x:Type avalonDockControls:LayoutAnchorableFloatingWindowControl}" TargetType="{x:Type avalonDockControls:LayoutAnchorableFloatingWindowControl}">
