End crystals don't render after being moved with pistons until the world is reloaded

The bug

When moving an ender crystal with pistons, it will disappear when the chunk it was originally in is no longer loaded. It will be visible again after the world has been reloaded.

To reproduce

  1. Set your render distance to 2 (only for easier testing; other render distances work as well, but then reproducing will take longer)

  2. Spawn an end crystal

  3. Move it with pistons for a while (for example with a flying machine)
    → ❌ At some point, the crystal no longer renders

  4. Close the world and open it again
    → ✔ Now the crystal renders from all angles again

Closely related to / caused by MC-44654, but as opposed to that ticket, this is possible in survival too!

I wasn't able to reproduce this in 1.20.1. I followed the flying machine for 5 minutes and the crystal stayed rendering throughout (render distance of 2 and simulation distance of 5).

Can you still reproduce this issue yourself?
