i know mobs can be pushed onto ladders but since when do they proceed to climb up them?

note in the pics provided, the cow is apparently pushed into the lower rung but then proceeds to climb and jump the rest of the way up and out of the pen.

not a big deal, but hilarious and surprising to load to.

update: i was using wheat to round up my cows and one of the cows still in the pen used the ladder to climb up and out in order to reach me... 

smart cow. im removing the lower rungs from all the pens...

on a final note, if this "fix" was intended, the change log needs to be updated to reflect the change.
