Make NSView NOT clip subviews outside of its bounds

Question

Is it possible to make an NSView not clip its subviews that are outside of the bounds? On iOS I would simply set clipsToBounds of my UIView no NO. But NSView doesn't have such a property. I tried experimenting with wantsLayer, masksToBounds, wantsDefaultClipping, but all of these seem to only change the clipping of the drawRect method, not the subviews.

After 5 hours of struggling I've just achieve it. Just change class of any NSView in .storyboard or .xib to NoClippingView and it will NOT clip any of it's subviews.

class NoClippingLayer: CALayer {
    override var masksToBounds: Bool {
        set {

        }
        get {
            return false
        }
    }
}
    
class NoClippingView: NSView {
    override var wantsDefaultClipping: Bool {
        return false
    }

    override func awakeFromNib() {
        super.awakeFromNib()
        wantsLayer = true
        layer = NoClippingLayer()
    }
}

Why do I override masksToBounds in NoClippingLayer? Because some native AppKit classes change this property of all sublayers in runtime without any warnings. For example, NSCollectionView do this for views of it's cells.
