The water texture on waterlogged buttons, leaves, and slabs renders too bright when placed under buttons, leaves, slabs, or any full block.

Steps to Reproduce

1. Find a dark space
2. Place a button, leaf, or slab
3. Waterlog it
4. Place a button, leaf, slab, or any full block directly above it within a 3x3 area

Here, the water texture will render brightly, even if there are no light sources around.

Original Description

it would seem that any type of leaves when placed above a waterlogged block (I don't know if it is all blocks that can be waterlogged, I only tested a cut sandstone slab and chest with all types of leaves) will create a medium level light source lighting up the water for about a 2 block radius.

I also attached a image of it
