Undo makes the scrollbar jump

Expected behavior:
I want to make a slight adjustment to the volume of a track, then repeatedly hit undo/redo to compare before and after.

Actual behavior:
I hit undo and all of a sudden the scrollbar jumps to the location of the PREVIOUS edit! If I hit redo, it DOESN’T take me back to where I was. So now I’m lost. I don’t know where I was. I’m not sure what’s been undone. It totally sucks.

I’m not sure if this is deliberate, but it’s really weird behavior and totally sucks.
