this bug appears in the newest snapshot 18w48a too.
this is just an simple example. if you want to reproduce it, just make postons working (pushing glasblock around)and let the game running. i don't know if the mobs spawn on the piston or on the extending piston head. abut somehow they are spawning.

few minutes later a mob spawned on the piston or the piston head and gets pushed through the glasblock.
made an example vid now.
