Steps to reproduce

1. Load MCPE-144446 item disappear.mcworld
2. Wait > 5 minutes.

Expected result

Stack of items does not despawn/disappear.

Observed result

After 5 minutes the stack of pressure plates disappears but it is still there server-side activating the pressure plate.

Stackable items will extend the despawn timer when items keep adding to them.

Problem: Items visually despawn but entities remain.

Expected outcome: Items will visually remain until the actual entity despawns.

Steps to reproduce: Have an etho-hopper-clock trigger a dispenser that dispense stackable items onto a closed enclosure to ensure that it keeps stacking the item in the same block-space. A pressure plate underneath to detect the items. What will happen is that after 5 minutes the items will visually despawn but the pressure plate will show that the items are still there and active. Unloading/reloading the chunk will reload the entity back visually. Moving out of render distance in y-level is insufficient.

 Additional info: another player entering the area will have its own visual despawn timer so it will disappear at different times per client.
