Clairvoyance into Dark Room

[Enig]

Using the clairvoyance spell on a darkened room will cause the room description to appear lit up (as it would if you could properly see) but mobs won't be visible and will be referenced as 'Someone'.

This happens if the character has normal or low-light vision but not if they have darkvision.

Looks like the helpfile needs more work before a non-caster like me can make sense of this...does clairvoyance not work indoors?

I assume in the case described, the PC should see only what they would see had they physcially walked into the room, correct?
