In spectator mode I saw a skeleton mob spawner and the mob in it didn't move.
*What I expected to happen was the skeleton in it to move like normal.
*What actually happened was the skeleton was frozen in place
Steps to Reproduce:
1. Do the command /gamemode spectator
2. Find a Skeleton mob spawner
3. It should not be moving
I don't know if it works on other mob spawners.
Spectators have no influence on the activity of mob spawners.
