Description of the problem

How to reproduce:

1. Find an underwater plant.
2. Place a bucket of swamp water inside of it.
3. Voilà, no more plant!

Expected result:

For it to place the water, but not change anything. Basically for it to act like a water source block.

Actual result:

It deletes the plant.

That's just how buckets behave? Does the same thing with any other plant

I guess this is also something to fix when 1.13 comes out. Maybe it'll end up being a Forge thing.

Here's me emptying a water bucket into a vanilla coral without deleting it.

Nothing to fix here, it's not a bug. It's working as intended just like in vanilla
