Happiness Isn't gained from non-active Pokemon Leveling

[Dreamblitz 1056]

So this may just be intentional Reborn meanness, but from what I can tell from research it doesn't work this way in the main games.

When a Pokemon levels up, it's supposed to gain +3-5 happiness depending on it's current happiness. However, currently it seems that this only applies when the pokemon is active in battle.
With my faithful testing dummy Budew, I found that it gained no happiness when leveled up both via EXP. Share, and through switch-training. When leveling up as the active pokemon or through a rare candy, it gained +5 as normal.

Sidenote: this makes common candies giving a corresponding drop in happiness for going down a level extra brutal.
