Creaking inside of cobwebs will occasionally stop while chasing their target

When a creaking is in cobwebs and chases the player, it will often stop, even right behind the player.

Steps to Reproduce:

1. Build a long (~10 blocks) strip of cobwebs, wide enough to trap a creaking
2. Spawn a creaking at one end of the cobweb strip
3. Stand at the opposing end (survival)
4. Let the creaking chase you through the cobweb
