In the latest Java snapshot of 21w43a, big dripleaf can now only be placed on clay, coarse dirt, dirt, farmland, grass blocks, moss blocks, mycelium, podzol, and rooted dirt.

However, on Bedrock, it still can be placed on more blocks that it isn't intended to.

Step to Reproduce
Place a big dripleaf on a block that isn't the said allowed block, such as end stone, or netherrack.

Expected Result
You can't place big dripleaf on blocks other than clay, coarse dirt, dirt, farmland, grass blocks, moss blocks, mycelium, podzol, and rooted dirt.

Observed Result
You can.
