When I set both light_source flags for media_interaction and
media_attenuation to off the attenuating media in the scene below still
affects the light and throws a shadow. This seems to be incorrect.
Scattering media still works as expected. When run through POV 3.1
everything seems normal.

#version 3.5;

camera {location  -z*4.0}

background{color rgb 1}

light_source {<-30, 30, 30> color rgb 1  
  media_interaction off
  media_attenuation off
}

plane {y, -1  pigment { color rgb 1 } finish{diffuse .8}}

sphere {  0.0, 1 hollow
  pigment {rgbf 1}
  finish{specular 0.6}                      
  interior{
   media{absorption rgb <0,1,1>}
   //media{scattering{1 rgb <1,0,0>*1 extinction 0 }}
  }
}
