[MCPE-165109] Most mobs get stuck on some incomplete blocks at the entrance to the water

Summary:
Mobs that can search a water such as axolotls, frogs, turtles are often stuck on the edge of incomplete blocks (mud, soul sand, dirt path, farmland) placed nearby and at the same level with water.

Steps to reproduce:

Make a pool (2+ blocks deep).
Replace the edges of the pool with the above incomplete blocks.
Spawn a mob nearby (frog, axolotl, turtle).
Follow the behavior of the mob when he goes to the pool.

Observed results:
Mob went to the edge of the pool and stopped.

Expected results:
The mob should enter the water when it goes to the pool.

Did you account for MCPE-122278 when testing this? (Make sure the water is at least 2 blocks deep.)

[Mod] EVGENSYPERPRO 2022-12-12T12:45:59Z

Yes. This happens in conditions of 2+ blocks deep.

Does the issue still occur for you as described?
I just tested and they get stuck as often and in the same way on full blocks as well.

The problem is still as described. There are no problems with full blocks. Try to reproduce the problem with dolphins. They always stay on the edge of the water until they die.
Here is a comparison video on full blocks and on mud with axolotls:

this has been a problem for so long I can confirm

The cause seems to be that when a mob is on block that is not full height its bounding box and/or exact location enters the bounds of the water block while the mob is still supported by the short block. A potential fix would be to condition the goal completion of moving to water on the mob's entire bounding box being inside a water block.

Thank you for your report!
After consideration, the issue is being closed as Won't Fix.

Please note that this is not the same as Working as Intended, as this bug report correctly describes behavior in the game that might not be the intended or desirable behavior, but it will not be fixed right now. Sometimes, this is because the issue reported is minor and/or impossible to change without large architectural changes to the code base.
