Hey there!

Maybe someone can help me figure this out:

class MyApp : App(Workspace::class, Styles::class) {
    init {
        with (workspace) {
            // This does NOT remove the forwardButton
            forwardButton.removeFromParent()
            // This does
            header.items.remove(forwardButton)
            // And so does this
            header.getChildList()?.remove(forwardButton)
        }
    }
}

However, the implementation of removeFromParent() says

when (this) {
        […]
        is Node -> {
            (parent?.parent as? ToolBar)?.items?.remove(this) ?: parent?.getChildList()?.remove(this)
        }
        […]
    }

The forwardButton is a Node and is created within a toolbar builder, so its parent should be set to that toolbar. Therefore, I’m a bit confused by the parent?.parent part on the left of the Elvis operator.
I then tried printing the forwardButton (which is a Button), its parent (which is null) and its parent’s parent (which in that case obviously doesn’t exist).

So, at which point in the Workspace does the forwardButton become an orphan?
