iOS 11 prefersLargeTitles not updating until scroll

Question

I implemented a basic UIViewController with a UITableView that's wrapped in a UINavigationController. I set prefersLargeTitles to true:

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.

    navigationController?.navigationBar.prefersLargeTitles = true
    navigationItem.title = "Coffees"
}

However, the title stays small until I scroll the view, at which point it enlarges. I tried moving that call to where I create the UINavigationController, but there was no effect. I am sure the navigationController is not nil when I set prefersLargeTitles.

Should I be updating that property elsewhere? Or should I file a Radar?

Update:

This only seems to happen if my view contains a UITableView or is itself a UITableViewController

I had the same problem. Although you are not using Storyboards but I hope this could help someone. I checked "Prefer Large Titles" for the Navigation Controller (not the View Controller) I embedded my TableViewController in. All the View Controllers after the Navigation Controller turned and had large titles, and it should work.
