When punching fire to extinguish it, it makes particles as a normal block does when broken. These videos are on Minecraft 20w10a with particles set to "minimal".
Steps to reproduce:
1: Start Minecraft 20w10a
2: Start any world (Edited because it happens anywhere, not just in the nether)
3: Find or create some fire and punch it
❌ ----> 4: It makes particles just like any other block does when broken

This sounds like MC-173731.

Looks like it's the same thing. Thanks for letting me know.
