DRAFT KB-XXXX Select all/deselect all prevents further selections being shown in a gridLayout

Symptoms

Symptom 1

Selecting the 'select all' checkbox in an editable grid and then deselecting all items stores an incorrect selection list. Please find an example below:

1. Create a new interface.
2. Create an editable grid with selection enabled and some way to be able to see the selected indices (i.e I used a text field to display the value)
3. Select all (with the top checkbox):
   
4. Clear selection with top checkbox:
   
5. You will notice: Selected: ;
6. Select an individual item, e.g. row 2: Selected: ; ; 2
7. Select another item, e.g. row 1: Selected: ; ; 2; 1

Note: Row 2 is deselected automatically, we still see 2 in the selected list and the top checkbox (all) is selected.
