Basically, the game is correctly tracking HP lost from the magic damage, but the transitions from gameplay camera -> Fury camera -> gameplay camera causes the game to incorrectly make it look like the Fury did more damage than it actually did, then "corrects" itself to show the actual current HP. It looks like healing, but it's just correcting and over-compensation.
I'm going to try and triple-check while looking at the internal numbers for HP before and after, but I've used him a lot myself and am almost certain that's what it is. Frustrating, but not technically doing anything wrong as far as combat functionality is concerned.
