What is the problem?

When making plastic in a biofactory, despite the building saying "output full", it continues to craft plastic until it reaches the item stack size.

Steps to reproduce

1. Build a biofactory
2. Assign it to make plastic
3. Feed the biofactory syngas and aromatics to craft plastic
4. Notice after some time that the building states "output full"
5. Also note that the building continues to craft, effective ignoring the "output full" state until the item stack size is reached

Additional context

Virtually all buildings in factorio after an output is full create a few more of the item, them stop crafting. For example, small parts will fill up to 15, even though the stack size is 200. The biofactory, at least when making plastic, seems to be an odd exception to this rule.

This is not a bug. Recipes that only take fluid ingredients and produces an item will buffer items till they have a full stack. Example of a vanilla Chemical Plant filling up to a full stack of sulfur.

The reason assembly machines in vanilla don't buffer a full stack of items is because inserters won't insert if the assembler has some buffered items. Pipes, however, are not so smart.

Keep learning, even after thousands of hours. Thanks for the clarification.
