Entities being ridden by skeletons do not face at their targets when attacking

Entities being ridden and controlled by skeletons do not face at their targets. This is noticable when fighting a skeleton riding a mob after being summoned by commands (e.g a pig being ridden by a skeleton).

To reproduce

1. Run the command

    /summon minecraft:pig ~ ~ ~ {Passengers:[{id:skeleton,HandItems:[{id:bow,Count:1b}],ArmorItems:[{},{},{},{id:target,Count:1b}]}]} 

2. Go to survival
   → The skeleton controls the pig, starts strafing, the pig is not oriented properly while the skeleton strafes.
