Mobs always tend to go higher incorretly.

• Short description of the issue

When mobs try to head somewhere and there are some blocks higher than the destination, they often step on the higher blocks first instead of taking the direct path. And sometimes they may even fail to reach, stopping on the higher place.

• Steps to reproduce the issue

This can be observed in these cases I have found:

In a house with a blast furnace, the villager wanting to find a job goes onto the smooth stone and can’t reach the blast furnace.

If the player hides in a lower hole and there are blocks higher nearby, the zombie trying to attack the player will step on the blocks first before turning to the player, though the blocks are farther away.

• Expected result

They are expected to take the direct path.
