Vertically retracting waterlogged blocks creates ghost water

Waterlogging a block that can be moved by sticky pistons, then retracting the sticky piston vertically with the block attached, the water will disappear server-side but not client-side.

Steps to Reproduce

1. Place a slab
2. Place a sticky piston above and facing the slab with one block of separation between them
3. Waterlog the slab
4. Activate the sticky piston
5. Deactivate the sticky piston

Here, a single water source will appear under the slab. Reloading the chunk/ world makes it disappear. Items do not float and entities cannot drown in this space.
