[MC-69067] Skeletons glitch in ground

I saw a skeleton in a cave, he was glitching in the ground

Did you punch the skeleton?
If so it's the same issue as MC-72868 (and not MC-119) and therefor fixed in 1.8.1_pre2.

Picture never showed he did...

That's why I'm asking.
The way the blocks are placed behind it make it likely that it's because he did.
