Blaze See Through Walls

When one blaze attacks me, all blazes become agro. For example, I will kill a blaze somewhere in a stronghold, then when I go back to my Blaze Spawner/XP farm, all of the blaze will see me from inside the room and shoot at me through the wall. They will not stop shooting until I kill all of them, even the new ones that spawn go agro. This is the MOST annoying bug in the game. Please, please, please, fix it ASAP.
