I've got a tree acting as menu for an application inside a panel. The
tree dataprovider is an XMLListCollection generated from a db call. I've
set the height of the tree to take up all the available vertical space
in the panel, so that there's no scrollbars when the user expands a
node.

When it renders, there's a black area below the top level nodes. I'm
thinking these are the default itemRenderers which have no content until
tree nodes are expanded.  But why are they visible at all?  I didn't see
this behavior in Flex 2, just the GMCs.
