Dripleaf is capable of deleting any block when growing

Small dripleaf plants will delete blocks above them when growing into big dripleaf. This includes blocks such as bedrock, which are not normally breakable.

Steps to reproduce:

Bonemeal a small dripleaf directly under a bedrock block.

Upon growing into a form taller than 2 blocks, the bedrock block above will be deleted and replaced with the big dripleaf.
