Problem description:

If you have a MenuItem with IsCheckable=True and StaysOpenOnClick=True, Windows Narrator does not announce when the IsChecked state is changed.

Actual behavior:

Windows Narrator does not announce anything when IsChecked is changed (e.g. the item is clicked on or the user types "Enter" while focusing it).

Expected behavior:

Windows Narrator should alert the user that the state has changed by saying "<MenuItem.Header> Checked" or "<MenuItem.Header> Unchecked"
