Blazes continue to track players outside follow_range, across dimensions

Blazes spawn with a follow_range attribute of 48 - as I understand, that means that if the player exits 48 blocks range, they should cease tracking that player.

I am experiencing blazes that, once they begin tracking a player, do not stop, even if the player goes hundreds of blocks away. They actually continue tracking the player's position even if the player changes dimensions. They stop tracking the player if the player disconnects.
