The Bug:

Particles render before the chunks that they're in.

A similar problem with entities (MC-242331) was considered to be a valid problem and was later fixed so one would expect this report (MC-265639) to follow a similar resolution.

Steps to Reproduce:

1. Summon a repeating command block that constantly summons stone particles around it by using the command provided below.

   /setblock ~1 ~ ~1 minecraft:repeating_command_block{Command:"particle minecraft:block minecraft:stone ~ ~ ~ 1 1 1 0 100 force @a",auto:1b}

2. Stand around five chunks away from the command block and reload all chunks by pressing F3+A.
3. Observe if the particles and rendered before the chunk that they're in.
4. Take note as to whether or not particles render before the chunks that they're in.

Observed Behavior:

Particles render before the chunks that they're in.

Expected Behavior:

Particles would only be rendered if the chunk that they're is in rendered as well.
