preferredStatusBarStyle for CFAlertViewController

[MartinP7r]

Sorry for asking a probably mundane question here, but would there be a way to set the statusbarStyle to lightContent for CFAlertViewController? I'm forced to use controller-based status bar appearance (because I need to hide the status-bar in an unrelated VC) and the rest of my app uses lightContent statusbars. I tried extending CFAlertViewController like so:

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

but that didn't change anything.
