Some mobs cannot pathfind their way through buttons below them and jumps when they are chasing something
Some mobs spawned on top of buttons (spawned from a spawn egg) will not move. Mobs that are chasing players or villagers will always jump around buttons similar to fire however they can randomly successfully pathfind through buttons while jumping.
To Reproduce
1. Spawn mob on top of button (make it 3x3 and crouch to spawn mob)
2. Mobs don't pathfind or move
Alternative version
1. Spawn hostile mob one block away from button
2. Go to survival
3. The mob chases you but jumps around the button and rarely stop

Description:
Mobs will try to walk and pathfind over buttons, but stop and start jumping as if they are trying to jump over the button. The mobs will not stop untill hit/pulled away from the button. After some testing, I can confidently say that I have seen it happen mostly with Horses in confined spaces (As seen in screenshots) and pretty much all mobs that can move on there own. This is a very annoying bug that should really be fixed.
Notes:
I have also observed that almost all other mobs will often get stuck while pathfinding over and/or onto non-solid/non-full blocks such as trapdoors, slabs, lower-half slabs, and similar blocks. Something in the pathfinding AI for mobs is clearly broken. I have seen variations of this bug happen many times on Android, Windows 10, and Xbox.
This bug also appears to relate to MCPE-46805 & MCPE-44575
How to reproduce:
1 - Summon a mob (such as a pig or zombie) in a closed off pathway made with blocks mentioned in the description of this report.
2 - The result is that the summoned mob will get stuck on the problematic block(s) and jump around.
The intended behavior should be that the summoned mob reaches the other end of the pathway (or other destination) without getting stuck on the problematic blocks.
This might duplicate/relate to MCPE-44575.
There is precedence for what Reed suggests in the comment just above, in the fix for MCPE-81316. That issue was fixed by changing the effect of collisionless blocks on a boat when placed on top of the ice the boat travels on, without changing the effect of those blocks on a boat when they are placed on the side of the ice that a boat travels on. So now blocks like buttons and torches are handled differently when in the same block as a boat than they are when in the block below. Doing the same for buttons and pathfinding could fix the issue reported here while preserving the fixes to MCPE-47075 and MCPE-44575.
See Precedence for differential handling of collisionless blocks attached to tops and sides of full blocks.mp4
for what I mean.
Missing 1.14.60.
The reason they path find like that is, there is this mechanic in Minecraft that mobs recognized buttons as a solid block. Thats why in mob farms in minecraft include buttons so that the mobs will walk to the edge on purpose. Sorry for bad english
And if you put it like that they think there trapped and they want to escape.
This issue was reportedly fixed in 1.16.100.52 Beta (as a side effect of the fix for
MCPE-47075). We will leave this ticket open until the fix is migrated into the regular release. No date can be given for that release.
