When having the gamerule mobGriefing set to false (/gamerule mobGriefing false) blaze balls still leave fire on impact with block.

A command block is not a mob.
mobGriefing prevents only changes to your world done by mobs.
It's no difference if you (or your command blocks) summon fireballs to you (or your dispensers) using flint & steel.
Cannot confirm.
Nothing burns with mobGriefing set to false.
Please double check by typing
