Waterlogging

Waterlogging is a mechanic that allows water to occupy the same space as all blocks that do not occupy a full block. This can be caused without a bucket with a debug stick. Debug stick goes to Java Edition only.

Mechanism
In Java Edition, certain blocks have a waterlogged = true/false tag.

In Bedrock an Edition, waterlogging is handled by the game's layers system. Through editing, any block can be waterlogged, as well as other things such as placing multiple slabs into a single block.
