When breaking a block, moving your head to where you aren't breaking a block will often make it retain it's cracks. When you go back to mine it, while still having left click on, it will continue where it left off. I tested this in single player.

Steps to Reproduce
1. Have a block.
2. Hold down left click. During this whole procedure, do not let go of left click.
3. Start breaking the block in front of you. Quickly, move your mouse so you aren't breaking the target block or any other block.
4. Repeat step 3 until the target block retains it cracks.
5. Move back to breaking the target block and it continues to break where it left off.

What was expected
I expected the block to lose its cracks when I stopped mining it.

This is similar to MC-62124, but not the same.
