DataGridView. Cells don't invalidate when setting setting Cell.Selected programmatically

Created attachment 275063 [details] Example 1. Compile attached code. 2. Click "Select cells" button. 3. Cells are selected but no visible selection, you need to invalidate the datagridview somehow to show selection. Expected: Cells invalidation (blue rectangle drawn)
Fixed in r127890 in trunk and in r127893 in 2.4 branch.
