Story Mode doesn't adjust your Planeswalker's life after a fight

Xibvert

Anywhere else in the game after a fight your Planeswalker's life total is adjusted to reverse any life loss that occurred during the fight and to add on any life gain your Planeswalker received while already at full life durinng the fight. But in Story Mode there's no post fight life adjustment and there don't seem to be any event rules that justify this difference.
