Water and lava surface is sometimes rendered from below even if there are blocks above

The bug

Flooded/underwater rooms get a ceiling of water as if reaching an air surface, even directly below a solid block.

If the solid block is replaced with a waterlogged block the "water surface" effect is removed. But a solid block produces the water surface effect. This is intermittent, it does not effect all blocks in this way, however I have been unable to determine why, or find a work around this purely visual, but incredibly annoying bug for anyone building under water.

I think it has something to do with proximity to glass, extending 1 block away.

To reproduce

  1. Build this structure and fill it with water
  2. Go inside
    On the edges of the room's ceiling, you'll see the water surface
  3. Break the middle block and replace it with glass
    Now the water surface is visible everywhere

It would be expected that the water ceiling only renders from above, but not from below.
