I have noticed that the BlockFertilizeEvent won't trigger when growing flowering azalea and normal azalea bushes.

In the pictures provided you can see how the spruce tree's it leaves and podzol blocks don't spread but the azalea tree does.

Method of reproducing bug with plugin:
1. Listen with BlockFertilizeEvent.
2. Loop through List<BlockState> on event.
3. Change block back to original block if in certain chunk.
