VBox bug?

Question

I met with weird behaviour of VBox layout.
When I put on the scene vbox defined like that:
var vb: VBox = VBox {
            width: 300
            height: 300
            managed: false
            content: [
                Button {
                    text: "Button"
                    layoutInfo: LayoutInfo {hfill: true vfill: true; hgrow: Priority.ALWAYS;}
        }Button has width=300px, but height is default (about: 20 px)
When i change VBox on HBox:
var vb: HBox = HBox {
            width: 300
            height: 300
            managed: false
            content: [
                Button {
                    text: "Button"
                    layoutInfo: LayoutInfo {hfill: true vfill: true; hgrow: Priority.ALWAYS;}
        }Button has width=300px and height=300px too.
Is it normal behaviour of VBox layout that doesnt set control's height?

I read this article several times, but I don' t see where the author explain that behaviour of vbox container.
The section which you have on mind, may be it:
+"Not All Containers Support Grow/Fill+
+It only makes sense for containers to support these preferences when nodes are in contention for space, so HBox supports it horizontally, VBox supports it vertically, and Grid supports it in both directions. "+
But this doesn't agree with my experience, where HBox (in my example) supports both directions, and VBox in only one direction (horizontally!!!).
