1. Place a dispenser with a bucket of water in it
2. Place a fire next to the dispenser (dispenser should face the fire)
3. Activate the dispenser
Particles appear like fire was a block which got broken
(Probably caused by the fix that water just deletes the block)
Duplicate of MC-33015, and several others. Ultimately caused by how MC-18342 was fixed. Working As Intended.
