Shown in attached video, tipped arrows with an assigned custom potion color do not emit particles but then randomly start to emit particles after awhile, but only for a second. This seemed to not be an issue in 1.20.4 and is now in 1.20.6

Steps to reproduce:

1) Use give command to give player crossbow with a tipped arrow containing a custom color component.

/give @p minecraft:crossbow[charged_projectiles=[{id:"minecraft:tipped_arrow",count:1,components:{"minecraft:potion_contents":{custom_color:16711680}}}]] 1 

2) Fire Crossbow.

3) Wait and see no particles emitting from arrows.

4) Wait further and notice particles start to emit from arrows.
