Description

Steps to reproduce:
1. Run program.
2. Click on a row.
3. Ctrl-click on another row so that two rows are selected.
4. Mouse down on this row to drag to the trash can.

Actual Results:

The first row selected becomes unselected on the mouse down to start the drag.

Expected Results:

Both rows stay selected.

Workaround (if any):

There probably is one but it involves a lot of code.

The Spark ListBase has special case code to handle this situation.

// If dragEnabled is true, clicks on selected contents should cause
// a selection change on mouse up instead of mouse down. Otherwise,
// clicking in a selection to drag will deselect any multiple selection
// before the drag occurs.
