Vertical layout automatic always have height 0 when using UIScrollView inside the sheet.

[pddkhanh]

Thank you for your awesome work.
I found there is a use-case that cause the height always is 0 when using UIScrollView inside the sheet ViewController. Could you please help to take a look and suggest how to fix it properly?

Below is the sample ScrollView within ViewController. This ViewController works normal with default presentation.

import UIKit

final class Label: UILabel {
    init(_ text: String) {
        super.init(frame: .zero)
        self.text = text

        textColor = .darkText
    }

    @available(*, unavailable)
    required init?(coder: NSCoder) {
        fatalError("init(coder:) has not been implemented")
    }
}

final class SampleScrollViewController: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()

        let scrollView = UIScrollView()

        let stackView = UIStackView(arrangedSubviews: (1...10).map { Label("Text \($0)") })
        stackView.axis = .vertical
        stackView.spacing = 8
        scrollView.addSubview(stackView)
        view.addSubview(scrollView)

        stackView.translatesAutoresizingMaskIntoConstraints = false
        scrollView.translatesAutoresizingMaskIntoConstraints = false

        NSLayoutConstraint.activate([
            stackView.topAnchor.constraint(equalTo: scrollView.topAnchor),
            stackView.bottomAnchor.constraint(equalTo: scrollView.bottomAnchor),
            stackView.leadingAnchor.constraint(equalTo: scrollView.leadingAnchor),
            stackView.trailingAnchor.constraint(equalTo: scrollView.trailingAnchor),
            stackView.widthAnchor.constraint(equalTo: view.widthAnchor),
        ])

        NSLayoutConstraint.activate([
            scrollView.topAnchor.constraint(equalTo: view.topAnchor),
            scrollView.bottomAnchor.constraint(equalTo: view.bottomAnchor),
            scrollView.leadingAnchor.constraint(equalTo: view.leadingAnchor),
            scrollView.trailingAnchor.constraint(equalTo: view.trailingAnchor),
        ])
    }
}
