This is marked as Resolved, but mobs with the leader zombie Health bonus still spawn with only 20 Health (I have experienced this on release 1.16.5 and on snapshot 21w40a).
My guess is that leader zombies get extra max hp, but they still spawn in with the default ammount of hp a normal zombie would have, or they spawn with 20 Health and the bonus is somehow applied after that.
