Breaking from the base is fine, but as noted in the drop tables for both fridge_light/dark (top half):

{"type":"minecraft:block","pools":[{"rolls":1,"entries":[{"type":"minecraft:item","name":"minecraft:air"}],"conditions":[{"condition":"minecraft:survives_explosion"}]}]}

Not that big a deal but adding it in here in case it was missed!

This doesn't seem to be the case. I just broke the top of the fridge but nothing was dropped.

Can second this, which was why I posted about it initially.
A datapack can work around it so it isn't an annoyance to other players in the meantime ocram sir.

It intentionally doesn't drop anything since the fridge is dropped by the freezer block.

Wait-- so just to clarify, if I as a player break the fridge from the top, me losing the fridge to the void is intentional?

Regardless which block you break on the fridge, the bottom will drop the item.
