But they attack endermites. The problem is that they don't search a way to pursue the endermites and stay at the same block.

Matthew Hunter, this bug is about broken pathfinding for enderman, which is different bug from MC-53518.
Enderman don't see slabs as blocks blocking they pathfind.

Razor Pan MADQVAC - walkaround - replace bottom slabs with full blocks.

In that case it duplicates MC-92466.

Thank you Michał, I'll try it.
