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.

Second repro command:

Attached debug profiles when running the command.

FPS drop persists until beacon beams disappear, but TPS seems to hold steady.

I would like to request ownership of this ticket because reporter is deactivated. Also affects 1.17 and 1.17.1 pre 1

Can confirm in 1.18.1.

Can confirm in 1.19.2.
