Tree Problem

[dgbarber]

There is a small problem when rendering a tree node with no children. The node label is rendered below the icon. The problem can be illustrated with the Icons example in the Showcase. Comment out all the child nodes. For example, I commented out all nodes but the first three, all top level folders. When the new case is run, the three folders are rendered with the folder name under the icon. Add the child nodes back and there is no problem. Possibly a CSS issue?
