Originally opened as https://github.com/flutter/engine/issues/820

To reproduce:

• click add a few times until you have a big block followed by a small block
• scroll the big block almost off screen, such that more of the block is off the top of the screen than the height of the small block
• tap the big block

The small block is moved off the screen and then there's a crash.
