Multiple mobs grabbing the same mob causes teleportation for the grabbed mob

[Atermonera]

Brief description of the issue

If two or more mobs grab the same mob, and then start trying to move around, the grabbed mob will attempt to follow behind the mob that most recently moved. Sometimes the affected mob will teleport directly behind the mob and sometimes it will be stopped by dense objects blocking a direct path between the two. All mobs will retain their grabs until dropped regardless of distance.

What you expected to happen

If Mobs A and C both grab B, and C pulls B away from A, A will lose their grab. This should probably respect grab strength too (such that a yellow grab cannot tear someone away from a blue grab)

Steps to reproduce

1. Acquire three mobs (at least two must have hands)
2. Grab one mob with two handed mobs
3. Move one grabbing mob away from the other, even out of line of sight
4. Move the other grabbing mob, observe movements of the affected mob.
