Pumpkins and Melons cannot grow onto mycelium and moss block

When you grow the pumpkin and melon, it doesn't grow onto the mycelium and moss block. This is a parity issue with Java Edition, where it can grow onto those blocks.

Step to Reproduce
1. Place down a small farm with moss blocks/mycelium surrounding it.
2. Plant some melon/pumpkin seeds.
3. Speed the random tick speed up.
4. See if they grow onto those blocks
---> It doesn't.
