When I clip inside a block connected to a water source, I see the moon instead of the sun, even when /gamerule DoDaylightCycle is false and it's day. I'm pretty sure this isn't supposed to happen.

Method to recreate:

• Dig at least 3 blocks below surface
• Fill every air block with water
• Switch to spectator mode and face west
• Move to where you can still see through blocks, but you're still touching the water (around .05 of a block)
