[MC-97628] Zombie aggro radius too high

Zombies aggro up to 32 blocks away, as soon as they can move. Other mobs will not aggro until the player moves to within about 16 blocks.

I reproduced this effect in the images I submitted. I built a cage for the zombie and markers to show distance. While the player stands on the red block, the red line at the cage mouth is 32 blocks away. While standing well behind the red block, the zombie in the cage is outside of the mob mobility range and it is frozen in place. I hadn't even reached the red block yet when the zombie immediately came to life and started heading toward me.

I believe this is WAI:

http://minecraft.gamepedia.com/Zombie#Behavior

"Zombies spawn in groups of 4 and will pursue the player on sight from 40 blocks away, as opposed to 16 blocks in other hostile mobs. As of 1.9[upcoming], the detection range of zombies is reduced to half of their normal range (20 blocks) when the player is wearing a zombie mob head."

That doesn't seem right. This just suddenly started happening recently. Also, mobs can't track the player from 40 blocks away because past 32 blocks away they become frozen in place.

Is this still an issue in the most recent versions (currently that is 1.10.2, or 16w43a) of Minecraft? If so, please update the affected versions and help us keeping this ticket updated from time to time. If you are the owner/reporter of this ticket, you can modify the affected version(s) yourself.

It seems to be less of an issue. In a series of 5 test runs, I got 2 zombies to detect me at 26 and 23 blocks, which is shorter than the previously reported 32 blocks, however it is considerably longer than the 14, 12, and 13 blocks at which I tested two creepers and a skeleton to detect me.

In gameplay, I have not been feeling that zombies chase me from abnormally far away, but it could be that I've simply grown used to the trend.

I feel like when I initially reported this, I had seen a zombie chase me from so far away that other mobs standing next to it were frozen in place. That no longer happens I am certain.
