I will not stop digging after I lift my finger from the screen(This issue happens randomly and with anything in the hand). Even when I walk around the game still thinks I'm trying to dig a block even though I'm not. The only way to top it is to place a block and it will stop digging. (This has caused a lot of damage so if it could be fixed ASAP it would be greatly appreciated. 

What I expected to happen was...

When I place my finger and hold to dig a block and then lift my finger I expect it to stop digging after my finger is off the screen.

What actually happened was...

**When I lift my finger to stop digging the game will continue to dig with the digging animation even when my finger is off the screen.

Steps to reproduce...

1-Start digging with any tool.(I always happen to be using an enchanted diamond tool)

2-Dig for a short bit and then stop digging.

3-You would continue to dig even when you stop.

4-Place a block to stop digging.

In the picture below I am walking and still digging. My finger is not on the screen except on the forward arrow to walk.(Notice how it is darker)
