MCPE-60160Mobs attempt to pathfind over walls that are lower than 2 blocks and higher than 1.5 blocks
With 1.13 an issue was fixed were mobs attempted to pathfind over 1.5 blocks high walls. MCPE-45256 But it hasn't fully been fixed. It still affects walls that are lower than 2 blocks and higher than 1.5 blocks.
How to reproduce:
- Place a full block like for example stone.
- Place a not one block high block that is not a slab above it. For example soul sand or an enchantment table or a bed.
- Try to lure a mob over the wall. For example lure a cow by holding wheat in your hand or just wait until it tries to do that itself.
What I observed: The mob infinitely tries to jump over the wall.
What I expected: The mob doesn't try to pathfind over the wall.
It does not work with 4 to 7 or more snow layers at one block, because all of them have a 0.5 blocks high collision box. (See MCPE-60024)

I created a bug report for this: MCPE-60160
Added a video, which shows
- The blaze stays still about 7 seconds after spawning before it starts jumping.
- When jumping blazes stay within a single block.
Both of these points suggest that this behavior relates to pathfinding. The jumping probably starts when the blaze begins trying to pathfind. The jumping is like MCPE-45256 and MCPE-60160 where mobs jump repeatedly when trying to pathfind to a block they cannot reach.
Thank you for your report!

Method 1 appears to be fixed by the fix for MCPE-41092 / MCPE-45800. I can still reproduce methods 2-5 in 1.17.11 Hotfix.
Methods 3-4 are the same as MCPE-47168.
Another repro method is described in MCPE-60160.
Confirmed on 1.14.20 hotfix by spawning a villager and a zombie in 1x2x2 spaces with an enchanting table on top of glass block in between them.
Affects 1.17.40.20
