1.13 : mass heal cannot heal all yellow 0 and not dead PC?

Hi,
With a "heal" spell i can heal a 0 or negative yellow character.
But not with "mass heal"? i would have thought it would have included those in the area spell? (since the resurrection or heal spell on such character "moves" them on the ground near the caster)
Is that normal?
