Commented Issue: Colour of PropertyGrid doesn't align with colour theme of Visual Studio [19560]

I have implemented a toolwindow with PropertyGrid from Extended WPF toolkit.
The propertyGrids colour doesn't align with the changed colour theme of Visual Studio.

I could change the Background of the PropertyGrid, but the list and sort button that comes with PropertyGrid doesn't changes it's colour.

Please refer the screenshot for the details

I have set the Background of the PropertyGrid to the appropriate key

I have done the following for PropertyGrid
Background="{DynamicResource {x:Static Microsoft.VisualStudio.Shell:VsBrushes.NewProjectBackgroundKey}}"

but still "Sort/Group buttons" still use the same standard colour,

Should it be changed in the Toolkit in such a way that the background colour of sort and group button inherits the colour from propertyGrid's background?
