Inventory of Villagers

Villagers of versions "1.14.3" and "1.14.4" are no longer collecting 8 packs of a single item, for example: seeds, wheat, carrots, potatoes, etc. But if you drop 4 packs of potato for example, I can drop 4 more packs of seeds as well.

In previous versions, villagers collected 8 packs of items quietly. Why are not you using this method of collecting items?
