[MC-237605] /setworldspawn causes simulated distance to fail in all loaded chunks

The Bug

When doing /setworldspawn with a low simulated distance it causes entities outside the simulated distance to be updated and act as if they were in your simulated distance

Reproduce

Set your simulated distance to 2 chunks
Put a zoglin and an armor stand next to each other
Move away to where they are outside your simulated distance
Look at the zoglin with a spyglass
✔ Notice it isn't doing anything
Do /setworldspawn
❌ Notice it starts attack the armor stand even though it is out of the simulated distance

Expected Result

/setworldspawn wouldn't cause simulated distance to fail

Does reloading the game fix this?

I'm pretty sure this happens because you're changing the spawn chunks to your current location

Spawn chunks are not affected by simulation distance. When you ran command, the spawn chunks changed to your location and likely allowed the mob to function.
