Apply visibility fixups for monsters triggering door trap explosions or digging through doors similar to the monster-opens- door-handling from a couple of days. Again, the issue is that hero/player can see a closed door in situations where they can't see an open one, and messages about the door being opened or destroyed need to take that into account when seeing a closed door go away. Not as thoroughly tested as monster just opening closed door.
