This did not immediately update the compass or anything; we should probably queue or send another fex/fei when we see this message.

Search the client code for handling the “It's light enough to see now!” message and the fei/fex compass or exit updates. Reproduce the glow example from the issue, then trace when the compass is refreshed; done means the visible exits or compass update immediately after the lighting message.
