If you place a sideways barrel in the configuration that allows for the barrel to drip its contents into the pot, nothing happens even with firepit automation on.

I open this request to ask for adding an up input to the PotBlockEntity 's "sidedFluidInventory" (similar to the one on for allowing the interaction between barrels in BarrelBlockEntity's "sidedFluidInventory")

This would allow not only for barrel-to-pot interaction, but also for piping interaction with other mods.
