When bonemealing a small dripleaf plant, it can destroy blocks, including obsidian and bedrock. The blocks don't drop, they're just deleted.
To reproduce
Place a small dripleaf plant on a clay block
Place a block above it
Apply bonemeal to the plant
→ ❌ The block is broken
Might require several tries to reproduce if the plant doesn't grow tall enough.
