Isolate and Save as JPEG

I needed a picture of a couple of parts in a large assembly today, so I thought "a perfect use for Isolate". Turns out it wasn't. Isolate works fine, but when I saved as a JPEG, I got a nice picture of all the parts, not the isolated parts. Is this a bug in one or the other or is my system just having a bad day?

The work-around was to pick the two parts, Invert Selection, Hide, save the JPEG, and Undo. Only one more click, but conceptually not as nice.
