Shift-Click block selection does not raise the SfDataGrid SelectionChanged event if selecting previous rows Completed

When using Shift-Click to select a block of rows in the grid the SlectionChanged event is not called if the initial selected row is below the row where the Shift-Click is executed.  For example select row 5 and then perform a Shift Click on row 3 with the intention of selecting rows 3-5.  Rows 3-5 will be highlighted indicated they were selected but the SelectionChanged event is not raised.  The event is raised if the Click-Select row is below the starting row (for example start with row 5 and do the Shift-Click on row 10).
