I then tried making the region of interest much smaller and got much better smoothing results.
This can be a bug. Unfortunately, we cannot reproduce it. Can you please provide additional information. What was the length (in frames) of your "long" region of interest (that had jitter problem after jitter removal)? What was your setting for "Trajectory Filtering (sharpen/smooth)"?

Also, when a project is saved, does it save the smoothed version, or the raw version?
It saves both. When you re-apply Jitter Removal it uses original raw animation data as input.
