toolbarBackground on macOS full screen

This sample code colorise the navigation bar, but while the window is in fullscreen or in splitView on the Mac, only the left sidebar is colorised.

How can be the full navigation bar be colorised also on full screen?

var body: some Scene
{
	WindowGroup
	{
		NavigationSplitView
		{
			ForEach(1..<3) { (i) in Text("\(i)") }
		}
		detail:
		{
			ForEach(1..<3) { (i) in Text("\(i)") }
		}
		.toolbarBackground(.yellow)
	}
}

@Luca_65 have you found any solution for this? I have the same issue myself. Cant find anything.
