I know a key contributor to rear-trunk condensation are bad seals around the lights. Top seals aren't usually the problem. As well, rusting of the inner wheel well can contribute to it.
I've not seen this on the frunk, but if not surprising particuarly for a vehicle that is parked outside at this time of year. The seals are the likely culprit in this location, unless you've got some perforation going.
