Floatable mobs are unable to walk when in waterlogged blocks

The bug

When an animal walks in water which is only a half block deep, they can't seem to move and spin in place.
This bug also happen to some hostile mobs that can float on the water, like creepers, spiders, silverfishes, illagers

How to reproduce

Spawn some pigs, using wooden half blocks, with the top half filled with water. The pigs move into the water, get "stuck" and instead of moving, will just spin in place. They can sometimes move a very small big/slowly, but mostly just spin in place.
