(Use MCPE-145830.mcworld to quickly reproduce this bug.)

Steps to reproduce

1. Place a partial-height block (carpet, bottom slab, trapdoor, unlit campfire, bed, etc.) or a block that has an open inside (hopper, composter, cauldron).
2. On all 4 sides of the partial-height block, at the same Y-level or at Y + 1 or Y +2, place blocks with collision that would prevent the piglin from moving. (In the case of a bed the blocks must be place around one end or the other of the bed, leaving a spot where a piglin could stand and be surround on all 4 sides by blocks.)
3. Toss a gold ingot to the the piglin.

Expected result

The piglin picks up the ingot and barters.

Observed result

The piglin does not pick up the ingot or barter.

after this update piglins in my bartering farm would not pick up gold ingots when standing on carpet or if they had fallen inside a hopper.  i locked the hoppers to ensure the hopper was not grabbing it before the piglin.  once i nudged the piglin onto the hopper's edge (top of a full block) he picks up gold every time.
