Description:

When bonemealing moss blocks, blocks that get converted to moss do not send block updates. This means that observers do not detect them being converted.

Steps to reproduce:

1. Place a moss block and some stone, or any other block with the moss_replaceable tag, nearby
2. Place an observer "looking" at the stone (or other) block, with a piston on its end
3. Bonemeal the moss block

Observed results:

While the stone/other blocks get converted to moss, the observer does not detect that and the piston does not get powered.

Expected results:

The stone/other blocks should get converted to moss, and the observer should detect that change and the piston should extend then retract.
