Mobs that try to pathfind over blocks with custom geometry just start jumping as if they're trying to get on top of a full block when there isn't one.
Update: 1.17.40.23:
 Vertical pathfinding seems to be pretty good now, but narrow blocks appear to be a problem for pathfinding, see attached video
Update: 1.17.40.20:
 In this update mobs can pathfind correctly over a custom slab (lower or upper), there still exists block heights that mobs won't pathfind over 2/3 for example.
Expected Behavior:
 Mobs pathfind over and around custom geometry correctly and smoothly.
Actual Behavior:
 Mobs start jumping up and down uncontrollably.
Steps To Reproduce:
 Download the attached pack
 Use the give command to obtain either 'grunt:mud' or 'grunt:basalt_slab'
 Place enough blocks to test pathfinding over
 Spawn a villager and a husk on opposite ends
 The husk will try to get to the villager but fail and end up jumping uncontrollably on the slab or just sit still on the mud
