At the top of the web inspector is a list of all the parent nodes of the currently top-most node. I would expect a parent to be listed above its children, with Document being top-most in the list. That's how the listing works in the tree view just below. However, the parents are listed under their children, making things look upside-down.
This matches the directory popup menu in the System's Open and Save panels. Should we differ?
This was fixed on the WebInspector refresh branch in r20715.
This was fixed on the inspector branch and merged to trunk in r20986.
