I figured out that building upwards into a new cubic sub-chunk will set the lighting to 0 in the sub-chunk above. Continuing to build upwards will make the dark region grow upwards as well.
This affects not only the chunk in which blocks are placed, but also adjacent and corner-adjacent chunks.

I have a lot of screenshots if you want proof.
