I have a component I'm developing to, among other things, accept an
XMLListCollection as a dataProvider (the data is being supplied via a
remote object call, which is why I've elected to extend a component to
handle the reopening /drag&drop, etc).

Best I can tell I've got working great, vice one issue that I just can't
seem to resolve.  Essentially, the first time the component loads it
shows the nodes in the tree at an apparently random height that is
significantly "taller" than what my normal tree node height should be. 
It would appear that the nodes are being spaced evenly across an
arbitrary height of the tree which is greater in height than the "100%"
I've specified for the tree to take up inside it's container.

I've included a screenshot of the behavior here, the left-hand image is
the initial, jacked up state, and the right-hand image is the very same
component instance after the contents are loaded the second time:

Any help you guys might be able to provide would be so very much
appreciated, I've been beating my head against the wall on this for
hours now.

Thanks in advance,
Brian
