Sneaking does not prevent the player from waterlogging blocks

Sneak to put water does not prevent the block you are pointing at (leaves, slabs, stairs) from filling with water.

Steps to Reproduce:

1. Place a waterloggable block
2. Obtain a water bucket
3. Sneak and use the water bucket on the waterloggable block

Observed Results:
The block is waterlogged.

Expected Results:
The expected behavior is that when crouching, the water is placed on or to the side instead of inside the block.
