End gateways and portals cause huge amounts of lag

The bug

End gateways and portals appear to have major effects on framerate when there is a large group of them, unlike any other block I'm aware of, and it's not just from the dual beam animation.

How to reproduce

  1. Run
    /fill ~4 ~10 ~4 ~-4 ~2 ~-4 minecraft:end_gateway
    

    →  Causes a very significant frame drop.

  2. Now, try to run
    /fill ~4 ~100 ~4 ~-4 ~2 ~-4 minecraft:end_gateway
    

    →  It causes complete unplayability.
