Villagers only have 8 inventory slots to store items, however, the client still shows villagers picking up items even when these slots are full and they have no space in their inventory anymore. Server-side the villager never picked up these items.
This started occuring in 1.14.2 Pre-Release 1. 1.14.1 didn't have this issue. Possibly introduced with the changes made to fix MC-140174.
When the player picks up these non-existent (for the client) items no pickup sound is played.
The bug is now slightly different in 1.14.3 Pre-Release 1: This does not occur for potatoes or carrots anymore. It looks like villagers can now only hold up to 4 stacks of potatoes, and up to 4 stacks of carrots, and will not attempt to pick up more than this. (Is that intended? I assume this was introduced as part of the fix for MC-74407, but it seems rather strange.) The issue still occurs for bread, wheat, and wheat seeds.

So....
The main thing that is described in this bug report has been resolved 6 days ago in a duplicate bug report at MC-153665 apparently, and the assignee for this bug report has been changed to no one a day after that happened, yet this bug report is still marked as in progress.
I still don't know the limitation that makes villagers only able to pick up a maximum of of 4 stacks for potatoes and carrots that was introduced at some point during 1.14.3 Pre-Release 1 is intended behavior. Is it? Is it not? Do I repurpose this bug report to be about that? Should a new bug report be created instead? Should this one be closed?
Farmer Wheat production is now broken in 1.14.3. the farmers no longer pick up more than 4 stacks of seeds which means they are able to pick up wheat... and when there wheat stacks fill up they no longer farm... also after testing farmers will throw carrots, potatoes, and beetroot but they wont throw wheat or bred...
