Rearranging the labels doesn't quite work in my case because the nodes have data associated with them and some nodes could gain or lose children during the update. Calling refresh() on the node is exactly what I'm trying to avoid because it creates a discontinuity in the UI.

I think it should be possible to change the sibling pointers on the DOM elements directly, as opposed to just the tree nodes, but I don't know if the browser will automatically rearrange the items when that happens. Anybody know for sure? I haven't tried it yet.
