StatusBarStyle suddenly not working in iOS / iPadOS 13, UINavigationBarController with Large Titles

I am using the following code to set the light colour for StatusBarStyle: But this code has suddenly stopped working in iOS 13 and iPadOS 13

extension UINavigationController {
    override open var preferredStatusBarStyle: UIStatusBarStyle {
        get {
            return .lightContent
        }
    }
}

I have implemented UINavigationBarController with Large Titles for iOS 13 and iPadOS 13. I am using Xcode 11.4.1
