Affects Version/s: Minecraft 1.12
Fix Version/s: None
After doing a /fill command over the mob_spawner the fire particles still remain until a player breaks the mob_spawner if it is placed in again.
What I expected to happen after the /fill command was that everything would be removed from the area.
The fire particles still remained.
1. Do /setblock ~ ~ ~ minecraft_mob_spawner
2. At the same spot do /fill (Position) minecraft:stone
3. Then do /fill (Position) minecraft:air
4. The bug should occur with the fire particles reamaining over.
