Yeah... uh...  :-)  ...only because the light source is no longer outside
the media container, as can be seen of the two lines shown arrowed, so it
doesn't need the pass_through anymore. And, having now tried your script
again I see that leaving the media's photon block out entirely actually
renders faster and is still okay I guess. From what I can tell in a small
rendering anyway.
