Clear selected programatically does not work

I need to clear selected programatically (Not the checbox in header), it does not work

http://jsfiddle.net/eyPzH/

Start with the reproduction linked in the issue and compare programmatic selection clearing with the header checkbox behavior. Trace the grid's selection-clearing entry point and verify the fix by reproducing the jsfiddle case; done means selected rows clear programmatically without relying on the header checkbox.
