20w12a confirmed. I reproduced this bug when i made a piglin go up one block in a 1 block tall air gap.

In 20w13a, it seems to mostly happens when piglins ascend or descend blocks, but also when the baby piglin moves closer to the edge.

1.16.1 confirmed. please reopen.

This issue is tracked in MC-163673.
