Created Unassigned: AvalonDock: How to create a new floating window programmatically [22542]

I'm trying to create a new floating window and am not having any luck.

I've tried using an approach like this:
```
LayoutAnchorableFloatingWindow f = new LayoutAnchorableFloatingWindow();
LayoutAnchorablePane ap = new LayoutAnchorablePane(item);
f.RootPanel = new LayoutAnchorablePaneGroup(ap);
dockingManager.Layout.FloatingWindows.Add(f);
```

But the window never appears.
