After transition occurs in NavigationDrawerController, black view cover entire screen.

Hi. I like your work. I appreciate this nice library.

I'd like to report an issue. I have an issue using NavigationDrawerController.
When I make transition from NavigationDrawerController with method transition(to:duration:options:animations:compeltion:), screen-sized black view comes up to front and cover entire screen. Please see screenshot below.

I tried to debug with Xcode, and I think that black view is contentViewController's view of NavigationDrawerController. In RootController's transition method, it puts new root-view-controller's view back in RootController, behind contentViewController's view.

I'm using Xcode 8.1, and tested in iPhone Simulator 7 Plus
the version of Material I used is 2.3.6

This is some of setting code in test application.
I made view controllers in main.storyboard, and instantiated them in AppDelegate.

// in AppDelegate.swift

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
        // Override point for customization after application launch.
        
        let orangeViewController = UIStoryboard(name: "Main", bundle: nil).instantiateInitialViewController() as! OrangeViewController
        let leftDrawerController = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "LeftDrawerController") as! LeftDrawerController
        let rightViewController = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "RightViewController") as! RightViewController
        
        let rootController = NavigationDrawerController(rootViewController: orangeViewController, leftViewController: leftDrawerController, rightViewController: rightViewController)
        
        let window = UIWindow(frame: UIScreen.main.bounds)
        window.rootViewController = rootController
        window.makeKeyAndVisible()
        self.window = window
        self.rootController = rootController
        
        
        return true
    }

// in OrangeViewController.swift (Main View Controller)
class OrangeViewController: UIViewController {

    @IBAction func tapButton(_ sender: UIButton) {
        let blueViewController = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "BlueViewController") as! BlueViewController
        blueViewController.view.alpha = 0
        AppDelegate.shared.rootController.transition(to: blueViewController,
                                                     duration: 1,
                                                     options: [],
                                                     animations: {
                                                        blueViewController.view.alpha = 1
        },
                                                     completion: nil)

    }
}

Thanks!

Hey, sorry about that, this was a regression. Please find a fix in Material 2.3.7 :) Thank you!
