Skeleton from Mob Spawners Do Not Drown

I attempted to use a skeleton mob spawner at a y of about 16 to farm arrows and bones using a simple drowning trap, however, the skeletons persisted well over a minute, and were clearly not drowning. I an attempt to 'update' them, I started fights amongst the skeletons and punched them, but to no avail. However, when I exited and reentered the world, some of the skeletons were suffocating in the block above the water and the ones who were not were drowning properly.
I replicated my drowning trap in a separate world on the surface but instead of using a mob spawner, I used eggs to spawn in the skeletons, and they drowned as intended in a short time.

UPDATE: The drowning location of the skeletons is flowing water from a source block one block away. This appears to drown zombies, players, and egg spawned skeletons, but does not drown mob spawner skeletons. If the drowning location is a source block however, the mob spawner skeletons still drown.

Try doing

/entitydata @e[type=Skeleton,c=1] {}

and check if there is a NoAI tag assigned to them. If not, try to find the Air tag (or something like that) and check the number for it, or you can just execute the command in a command block and copy and paste the result here.

The command does not appear to work, giving back a "Usage: /entitydata etc.." I can assume there is an AI tag, as they do shoot at me and at each other. There is indeed an Air tag, but I was unable to find (so far) how to format a command to search.

Can you attach the affected world?

The file size is too big 😛.

Did you do any modifications to your world? For example, played with mods before, using Optifine, MCEdit, etc? Maybe you can try F3 + C and attach the crash report here?

No mods have been used - just Vanilla.

Here's the crash file:
