When a player ignites a creeper with a flint and steel, the mobs that the creeper kills do not drop xp or player drops.

I reported this as seeing as the player is the root cause of the creepers explosion, the mobs that the creeper kills should be the result of the players actions, similarly to how blowing up tnt counts towards the player too.
