2010 SP3 Tree Document Order

I'm testing SP3 on a VM and noticed that when I transition a file the reference tree is ordered in such a way that the selected file isn't at the top.  The files are ordered by file name in aphla-numeric order...with no regard to parent-child relationship when sorting.

Anyone else notice this?  ...Setting? ...Bug?
