[MC-172509] Entities in lazy chunks can be killed, but don't play their death animation until the chunk is reloaded

The bug

Mobs in lazy chunks can be killed using /kill, but their death animation doesn't play until the chunk is loaded

To reproduce

Set render distance to 2
Move away from the spawn chunks
Summon ac ow with NoAI
```
/summon cow ~ ~ ~ {NoAI:1b}
```
Move 3 chunks away
Run /kill
Wait for a bit (long enough for the death animation to play)
Go back to the cow
→ ❌ The death animation is played as soon as you are near the cow

can you please attack the log files. Also if you can reproduce the issue please do /debug start wait for some time. Then do /debug stop and do /debug report and attach the debug files in your %Appdata%\Roaming\.minecraft\debug directory

Can confirm. As far as I'm aware, this is an intentional mechanic though, as entities stay loaded in lazy chunks (which the chunks at the edge of your vision are), but don't actually move / aren't actually processed.

Can confirm in 1.17.1.
