Campfire smoke stays while chunks are not loaded.

I noticed this in 1.15.2 on my server where i use campfires for decoration purposes and when I go further away from them I notice only smokes while chunks are not even loaded there. So I jumped to see if this was fixed in 1.16, but it seems like its not.

To Reproduce:
1. Place a campfire.
2. Set draw distance to low (2 chunks is used in screenshot). (Also on my server I use 10 draw distance with optifine so no fog is there and it is easier to see this issue).
3. Watch.

I would really appreciate if you would take care of that. Thank you!
