Start HelloListView, select item 2, press shift, select item 7:
SelectedIndex: 1
SelectedIndices: [1], removed: [], addedFrom: 0, addedTo: 1
SelectedIndex: 5
SelectedIndices: [1, 2, 3, 4, 5], removed: [], addedFrom: 1, addedTo: 5
Press Delete 0th row.
Only 4 selected items remains, item 2 gets unselected.
SelectedIndex: 4
SelectedIndices: [1, 2, 3, 4], removed: [], addedFrom: 0, addedTo: 5

Now if the order of the selected items is reversed, that is:
Select item 7, then shift-select item 2:
SelectedIndex: 5
SelectedIndices: [5], removed: [], addedFrom: 0, addedTo: 1
SelectedIndex: 1
SelectedIndices: [1, 2, 3, 4, 5], removed: [], addedFrom: 0, addedTo: 4
And then press Delete 0th row, the selection shifts correctly:
SelectedIndex: 0
SelectedIndices: [0, 1, 2, 3, 4], removed: [], addedFrom: 0, addedTo: 5
