Description

When scrolling with "flick" gesture (finger is placed on the screen and quickly swiped in the desired direction), grid scrolls to the end or start of grid and then automatically selects last/first row.

Example: http://plnkr.co/edit/sgabAH1eZJEIHp78qgXM?p=preview Note: grid is situated to accordion to better see this behavior. Maybe there is some setting I have missed.

Research direction
Investigate the flick gesture handling in ui grid. The plunkr (http://plnkr.co/edit/sgabAH1eZJEIHp78qgXM) reproduces the issue. Look at the grid's touch event handling code, possibly in files like 'ui grid touch.js' or similar. Focus on how row selection is triggered when scrolling reaches boundaries. Consider if this is a regression or an intended behavior that should be configurable.
