Vanilla surface fog "bleeds through" when exploring large unlit caves.

Not sure if this qualifies as bug but due to massive cave size introduced.

The vanilla fog seeps through the cave system when cave is big enough (which happens a lot more often now) and render distance is low enough (i'm playing on 10 chunks render distance for performance reasons)

It "artificially" lights up the cave and looks very "unnatural" for the lack of better word.
