Blocks are not destroyed when you hit them on survival mode.

Blocks that don't destroy themselves when you hit it on survival mode.

What I expected to happen was....
For the player to destroy the block and collect it when it drops on the ground.

What actually happened was...:
The player destroys a block but it doesn't drop on the ground and the block i tried to destroy reappears and it keeps repeating this process and therefore cannot collect the block i destroyed. (This is on Survival Mode not Adventure and is not on a server)

Steps to Reproduce:
1. Start first by creating a new world on survival mode
2. wait for world to load and spawn player
3. Try to hit or destroy a block from a tree or anywhere.
4. And from there the bug should start to affect the block your trying to collect.
