Tamed animal teleportation minor bug concerning the destination

Tamed cats, parrots and dogs teleport after the player, if they're getting too far away. This teleportation does not happen if there are no eligible destinations for the animal.

• They do not teleport to a 1x1x1 space, despite they are small.
• They do not teleport o a 1x2x1 space if the upper block is transparent, such as:
  • Glass
  • Trapdoor
  • Hopper
  • Half slab
• They do not teleport o a 1x2x1 space if the lower block is one of the following:
  • Pressure plate
  • Half slab
• They do teleport despite:
  • There is a carpet,
  • There is tripwire,
  • There is a scaffolding block in the destination.

I'm not sure which of these are intended or not. But it feels weird.
