> * The last column of a {{DataGrid}} can be sized to end before the grid ends.
> * Although this space between the last column separator and the end of the grid looks just like the last column header (which in fact it is), {{GridColumnHeaderGroup.getHeaderIndexAt()}} returns {{-1}}, falsely indicating that there's no column under the mouse pointer.
> * Moreover, the {{GridColumnHeaderGroup}} does not dispatch the {{GridEvent.GRID_ROLL_OVER}} and {{GridEvent.GRID_ROLL_OUT}} events for that part of the last header.
