Overworld vegetation cannot be placed on soul soil or nylium

Th bug

Overworld vegetation cannot be placed on soul soil or nylium. And if the nether vegetation can be placed on soul soil and even the overworld dirt blocks, why can't the overworld vegetation do the same?

Affected blocks:

1. Bamboo
2. Flowers (Wither Rose in MC-171120)
3. Fern
4. Grass
5. Sweet Berry Bush
6. Saplings (It wouldn't make sense to be possible for them to grow into trees on nylium/soul soil though)
7. Sugar Cane
