Enderman AI causing HIGH ms tick lag

When going to the end, the player's MS ticks are raised up very high and the player starts to experience the enderman's movement starting to lag.

Cannot reproduce. Can you please create a debug log while in the end? This can be done by running "/debug start" then after about a minute or so, "/debug stop". A debug log will be created in your Minecraft directory. Attach it here.

Debug now attached to post.

Was the ender dragon still alive? Were there a lot of endermen?

The enderdragon was not still alive, and after some testing on my world I found out that the MS spikes come from making the endermen agressive to the player. 

Confirmed for snapshot 19w13b

Thanks. I marked as related just in case that is the cause.

Can confirm for 1.14-pre5.

Can confirm for 1.14. Although it does not really affect casual playing. Only endermen farms (50-70 endermen stacking in a 3 by 2 spot and trying to teleport to the void when hitting them).

Its rather when they are trying to move over to the endermite. (might be leaves messing up with the pathfinding, dunno).

Still in 1.14.1 pre1 - see attached screenshot and profiler dump
