The Bug:
Vindicators have short range and cannot attack players that are 2 blocks tall, however, when riding a ravager their range increases with an extra 2 blocks which causes vindicators riding ravagers to be able to attack players 5 blocks tall.
To Reproduce:
Do /summon ravager ~ ~ ~ {Passengers:[{id:vindicator,HandItems:[{Count:1,id:iron_axe},{}]}]}
Build a 5 block tower
Go to survival
Works as intended, vindicators when riding ravagers are taller and in return; can attack higher
