If you summon an invulnerable passive mob and set it on fire, it will run around as if it were taking damage even though it isn't.

This has apparently been fixed in 1.10-pre2 (MC-102408).
Is this still an issue in the current Minecraft Snapshot 15w49b or later? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.
