Feature Tree Highlight Jumping

I've been noticing lately that when I expand a feature tree item... say a hole feature. My highlight moves from the selected feature to the top of the feature tree. Now that I'm trying to figure out what causes it, I can't seem to get it to do it on purpose. Has anyone else noticed this? It happened to me a lot yesterday and was significant because I have hundreds of hole features and when more than the hole of interest has already been expanded I lose which hole I was trying to expand. (expand: expose the driving sketch features) If you've experienced this, do you know the scenario that causes it? I didn't find any other posts about it and it's disrupting my workflow.

 

EDIT: It just happened to me again, but after it happens, it will not repeat the behavior... but if I close the file and open it again, it at least consistently happens the first time.
