Rounded corners on iOS 13b3

When launching the app on iOS 13b3, the screen corners will be rounded. This effect disappears after switching navigation controllers.

What I have found so far is that accessing to tabBarController.tabBar.topAnchor in AppCoordinator.swift turns corner to round.

Currently, we read this property to assign playerDisplayController.realBottomAnchor, but replacing it with print(tabBarController.tabBar.topAnchor) will also (???) get the app have round corners... I do not understand why though. tabBarController is a conventional UITabBarController, so it's Apple's .tabBar and .topAnchor.

I also found that changing superlayer cornerRadius / masksToBound will get VLC to have square corners, but it's not what we want I think. (self.window.rootViewController.view.layer.superlayer.cornerRadius = 0; in delegate)
