Go to this grid and try to scroll vertically using touch emulation (not mouse) in chrome you will see the first, second, third columns do not scroll down but last pinned column will scroll.

Tried in a couple browsers Chrome Version 49.0.2623.87 (64-bit) iOS Mobile safari 9.3

Research direction
Reproduce the issue using the provided Plunker link. Investigate the touch event handling for scroll in ui grid, particularly for pinned left columns. Look at the grid's scroll event listeners and differences between pinned and non pinned columns. The issue likely resides in the grid's scroll implementation for touch devices.
