Feeling jumpy about jumpy scrolling

Here's a scary scenario for hallowe'en

Sometimes when I collapse a track folder, my whole page jumps up. It seems like sonar is trying to be helpful by making sure that the screen is always filled with tracks, but it feels erratic and counter-intuitive because I lose my place. I then have to hunt up and down to find my position again.

I would love to disable this helpful behaviour. Any setting I am missing to accomplish that?

Cheers
