When the villager walks on blocks not listed in "minecraft:preferred_path" (like Grass Block, for example), and then tries to reach their Bed to sleep, they will constantly stop moving and then continue for every 8-11 blocks.

Steps to reproduce:

1. Summons a Villager, and then place 2 Bed, wait until green particles appears
2. Changes the time to night and let the Villager sleep
3. Move far away from Bed and then spawn a new Villager
4. Observe

Expected results:
Villager walk towards the Bed without stopping, unless attacked.

Observed results:
Villager will stop moving after 8-11 blocks, then continue, this will keeps happening until they finally reach their Bed.
