Farmers that harvest wheat and has no means of throwing bread away will eventually empty their fields, leaving bare farmland.

Description:
When a farmer has tended a wheat field for a long time, the farmer will eventually stop resowing the farmland with seeds, leaving instead only empty farmland. In time, the area of farmland may be emptied entirely of crop.
I suspect it may be because farmers inventory become occupied with wheat, leaving no space to pick up seeds. The farmer is expected o pick up seeds along with the harvest, which ought to prevent an inventory slot from becoming entirely empty. Nevertheless, it seems to be what is happening.
I attach 3 pictures showing the issue. I made 4 fields of farmland and gave 4 farmers different prerequisites in order to accentuate the error. Tick speed is 10, and pictures show the progression over roughly one hour:
On top left, farmer is given 1 stack of seeds. We see the farmer planting, harvesting and resowing. No issues show up.
On top right, farmer  is given a full inventory of seeds, 8 stacks and a resupply once the field is planted. We see the farmer harvesting and replanting, with excess wheat piling up on the ground, also excess bonemeal.
On bottom left, farmer is given 1 stack of seeds and 7 stacks of wheat. We see the farmer harvesting and replanting for a short while, then suddenly harvesting but not replanting. Seeds are seen left on the ground, but wheat is still picked up. Possibly because the farmer has wheat in all 8 inventory slots.
On bottom right, farmer is given 7 stacks of seeds and 1 stack of wheat. Behaves same as top right.
Issue may possibly be seen in continuation of MCPE-123412 (solved). However, crop is no longer lost, since it may now be picked up by the player. In this ticket, the harvested crop may also be picked up by the player, but the farmer does not replant.
To reproduce:
Create a field of farmland, possibly 9x9. Create a farmer, and bed and composter. Give the farmer wheat seeds. Wait.
Farmer keeps on harvesting and replanting wheat. As time goes (many hours at tick speed 1), and the farmer does not have opportunity to throw away any bread, the wheat is at some time left on the ground, indicating a full inventory.
Expected result from here:
Farmer keeps on harvesting and regrowing, leaving excess wheat and seeds on the ground.
Observed result:
At some time, farmer keeps on harvesting but does not replant. Fields becomes empty.
