If you dip a non-inverting remain in a fountain of inversion (This particular bodypart doesn't seem to invert!) the fountain of inversion still loses charges and is accordingly depleted.
Interesting; I was about to claim this was expected, but you're right, if you had mixed a potion with the same remains, the potion wouldn't be consumed. Will fix.
