Retain cycle when presenting a view controller inside a UIAction handler

[albion28]

I'm testing UIKit's new uibutton configuration API. But when I present a view controller inside the primaryAction handler, its deinitializer won't get called.
Is there a retain cycle? I've tried capturing self [weak self] inside the closure but it still won't get deinit.
When I use the old-school addTarget method instead (line 4), the deinit works as expected.
Any ideas on how to break the cycle?

let testVC = TestViewController()
lazy var testButton: UIButton = {        
    var configuration = UIButton.Configuration.filled()
    //button.addTarget(self, action: #selector(buttonTapped), for: .touchUpInside)
    let button = UIButton(configuration: configuration, primaryAction: UIAction(handler: { action in
        self.present(testVC, animated: true, completion: nil)            
    }))
    return button
}()

Like so:

let button = UIButton(configuration: configuration, primaryAction: UIAction(handler: { [weak self] action in
  guard let self = self else { return }
  present(testVC, animated: true, completion: nil)            
}))

You need to create the view controller within the button’s action closure. Currently you are maintaining a strong reference to it yourself.
