Vanilla behavior prevents a chest from being opened when any entity is on top of it

Yes, but it's not game-breaking, there lots of more issues that are game-breaking so i think they'll be focusing on them first... This may not be changed soon or may not be changed at all because it's a little insignificant. Btw, it's still good to report issue to make pmmp better.

any _living_ entity.
