I have the same problem.

1.  The last selected item in multiple selections has a "focus box" around
it.
2.  If the focused item is deselected, it is not highlighted anymore, but
the focus is still on it. No sel change event.
3.  If another highlighted item is deselected, it is not highlighted
anymore, and the focus move to it. There is a sel change event.
4.  The focused item is considered selected, regardless of highlight state.

This behavior is annoying. Anyone has a solution?
