Baby zombies are unable to hit or catch up to a walking player

When chasing a walking player, baby zombies are, despite having a faster movement speed, unable to catch up or attack. When they get close, they stop for a moment before they are near enough to attack, and then they resume chasing. Previous reports of this bug are marked as Resolved even though it persists.
How to reproduce: Summon a baby zombie and go into survival mode, then start walking away from it.
