Door glitch?!

Battlecat45

I know there are games like a pay away, last qbee standing on bottomless enviroment and PVP wars. There are people passing through portals (middle) an when they jump, they can go to a roof from a room (glass for example)! This is very crazy! Please moderators: check if it can be fixed :)

Leave an empty space along the top of the doorway to prevent. One block height will be enough.
