A Transfer Node with a Stack Upgrade and a Filter is attached to a large inventory (a Controller Slave from Storage Drawers). While the node is filling its internal buffer from the inventory, it will go through each inventory slot and check if it matches the filter. If the slot does not match the filter (no items are extracted), and the node has a Stack Upgrade, it will call markDirty on the inventory for each non-matching slot.
