Is it possible to make the top edge like left/right/bottom? (3D decoration only, no titlebar)

I have tried removing all titlebar items and lowering titlebar_height to a small value like 4-5, but the top edge's rendering is simply different from the rest so it doesn't achieve a nice seamless look no matter what.

local nice = require("nice")
nice {
	titlebar_height = 4,
	titlebar_items = { 
		left = {},
		middle = {},
		right = {}
	}
}

Is there a built-in way to achieve this that I might have missed?
Thanks!

Actually I answered my own question mere seconds after making this issue. Just need to set the titlebar radius as well!

nice {
	titlebar_height = 3,
	titlebar_radius = 3,
	titlebar_items = { 
		left = {},
		middle = {},
		right = {}
	}
}
