Non-solid blocks make no sound when placed in water

Non-solid blocks like Hoppers, Slabs, and Kelp make no sound when placed in water. They do when placed on land. I am only using a classic texture pack, which does not affect sounds.

Steps to reproduce:

• Place a non-solid block, like a Hopper, in water.

Expected result:

• The block makes a sound when placed in water.

Actual result:

• The block makes no sound when placed in water.
