Combat Bug

[Voidwiggles]

Description: When I heal with my shammy on Cursed Island, it puts me in combat for another 5 seconds even if all the mobs die. I noticed this with another shammy healing Cursed Island. I forgot to take a screenshot while doing Cursed Island

Current behavior: Healers are staying in combat even after all the mobs are dead

Expected behavior: If all the mobs are dead, combat should end

Steps to reproduce the problem:

1. You should see it if you heal someone in combat right before the mobs die. I've only healed on Cursed Island recently.
