When Happy Heart boxes are in "non-vanilla" locations, they don't act like normal Happy boxes

I've found that every Happy Heart box has the flags of a normal item rather than of a pushable box. Meaning that, when interacting with a box in a non-vanilla location, Chibi picks up it and holds it over his head, instead of grabbing it to push/pull like a normal box. They also do not explode when hit with the charged Chibi-Blaster, making it impossible to break them for the happy points.
