Upon fighting the ender dragon, when attacked, the ender crystals explode and the fire animation stops, but the crystals remain and still heal the dragon.
I can't seem to be able to reproduce as, when recreating the same environment (Superflat, Void preset, /setblock ~ ~ ~1 end_portal, then destruction of a crystal with a snowball), the bug doesn't reappear. Furthermore, the previously broken crystals disappear upon re-entering the world.
Is this still an issue in 15w44b? If so, please explain the issue in detail and provide steps to reproduce it. Please also update the list of affected versions.
