BUG when the light is on the wrong side of the object (light hiden behind a plane it should not light the plane)

on the screenshot there is two lights (the classic light that creates shadows on the botom plane and on the top and right plane) plus I added a light under the botom plane it's enlightening the side of the plane that should not be lightened (it should just block light somehow)
