When using the EVA jetpack on Mun or Minmus, thrusting up (away from the surface) adds a forward velocity component, and thrusting down adds a backward velocity component. This does not seem to happen while in orbit (at least not that I've been able to notice). The navball velocity mode (orbital vs. surface) does not seem to make a difference.

Severity: Medium

Steps to reproduce:

1. Launch a vehicle with a Kerbal aboard and land it on the Mun.
2. EVA the Kerbal.
3. Controlling the Kerbal, go down to the ground, then move a short distance away from the landing vehicle and face it.
4. Activate the Kerbal's EVA jetpack.
5. Hold the left Shift key until the Kerbal rises above the height of the vehicle, then release the key.
6. Observe the Kerbal's path.

Expected behavior: The Kerbal lands in the same place it started from.

Observed behavior: The Kerbal jumps over the landing vehicle.
