Selecting multiple rows using Shift key

After selecting multiple rows using the shift key the grid then fails to clear the selected rows correctly and also I am unable to update the row data for the selected rows.

I think the issue is related to grid.$$selectionPhase not getting set to false after the multi row selection using shift key.

KoGrid.js - Line 1817: return true; is called and grid.$$selectionPhase is not reset to false;

Start in KoGrid.js around line 1817 and reproduce multi-row selection with the Shift key. Trace the selection phase through selecting, clearing, and updating rows, then verify that both clearing selected rows and updating their data work correctly after a Shift selection.
