## About The Pull Request

fixes #80946 

not sure why it borrowed the wrong commit msg

## Why It's Good For The Game

on the one hand it's funny but on the other hand it's dumb to be able to
buckle massive mobs to tiny-sprite objects they might not be able to get
out of without just destroying their own chair - assuming they can,
which in the case of some things you can buckle to, you can't (looking
at roller beds.)
