material3TopAppBar/preferCenterAlignedStyle not working...

I have been unable to get preferCenterAlignedStyle (and material3TopAppBar) to work. It seems to be ignored, always aligning the title (text or image) to the left.

.toolbar {
	ToolbarItem(placement: .topBarLeading) {
		// Left button here...
	}

	// Center logo - doesn't center on Android even with preferCenterAlignedStyle: true
	ToolbarItem(placement: .principal) {
		Image(systemName: "star.fill")
	}

	ToolbarItem(placement: .topBarTrailing) {
		// Right button here...
	}
}

As I understand it, these modifiers are unusual in SwiftUI in that they must be placed outside of the view they affect. I've applied this in a number of places, including at the app root, to no avail.

#if SKIP
.material3TopAppBar { options in
	return options.copy(preferCenterAlignedStyle: true)
}
#endif

I have attached a screenshot and a simple code sample showing this behavior.

Start with the attached toolbar-demo.zip and reproduce the alignment on Android using the ToolbarItem placements shown. Trace how material3TopAppBar and preferCenterAlignedStyle are applied to the toolbar, then verify that the principal text or image is centered when the option is enabled.
