not my valve stem's keeper

Front left cylinder exhaust valve has dropped past the valve keepers & spring retainer. No compression in this cylinder. The valve keepers remain in place; see attached photo: the keepers are there, but the valve has dropped. How does this happen? My mechanic is puzzled. Any thoughts or suggestions are appreciated. The tear-down continues.
