I think this also prevents using CheckSight with portals to hide/remove particles based on visibility to the player, because portals in most cases will have blocking lines around them.
At least I most definitely remember CheckSight not working properly in such cases which led me to the assumption that CheckSight is not portal-aware at all (but apparently it's a bug).

Also, making the blocking line (highlighted one here: http://i.imgur.com/uakCxCe.png) doublesided and passable solves the problem and the imp from the left room can see the player too.
