Describe the Bug

Attempting to drain liquid from a stackable container (in my case Tech Reborn cells) drains one bucket's worth of liquid and lets the full stack continue along the conveyors. There's also some other weirdness which ended up giving me more cells that I started out with, but I haven't been able to pinpoint what exactly is happening there quite yet.

Reproduction Steps

1. Set up an item drain with a conveyor belt going in and out, and a fluid pump connected to a tank
2. Drop a stack of fluid containers on the belt
3. Some of the fluid should end up in the drain/tank, while the stack of containers continues along on the belt unaffected

Expected Result

Unsure? Either only one container let onto the drain at a time or only one empty one leaving at a time. I guess this situation doesn't come up with just vanilla + create.

Additional Context

No response

Not sure whether I should edit the original post or send a comment like I'm doing but I see what's happening with the additional cells being created. Whenever a stack of cells is ready to get on the item drain, it will wait just before, presumably to let one on when there's space in the drain for fluid. What happens instead is one cell gets subtracted from the stack, but what's supposed to be a single cell landing on the drain is actually the full stack, duplicated.
