.intrinsic size conflicting constraints

[SaladDays831]

I'm getting conflicting constraint errors even with the most basic setup when using .intrinsic size

class DemoViewController: UIViewController {

    private let demoView = UIView()

    override func viewDidLoad() {
        super.viewDidLoad()

        view.addSubview(demoView)
        demoView.translatesAutoresizingMaskIntoConstraints = false
        demoView.topAnchor.constraint(equalTo: view.topAnchor).isActive = true
        demoView.leadingAnchor.constraint(equalTo: view.leadingAnchor, constant: 16).isActive = true
        demoView.trailingAnchor.constraint(equalTo: view.trailingAnchor, constant: -16).isActive = true
        demoView.bottomAnchor.constraint(equalTo: view.bottomAnchor).isActive = true
        demoView.heightAnchor.constraint(equalToConstant: 200).isActive = true
    }
}

func buttonPressed() {
        let controller = DemoViewController()
        let options = SheetOptions()
        let sheet = SheetViewController(controller: controller, sizes: [.intrinsic], options: options)
        self.present(sheet, animated: true)
    }

This results in these conflicting constraints:
