JDK-8285698 - Create a test to check the focus stealing of JPopupMenu from JComboBox
Description
In 1.4 showing a JPopupMenu now moves focus. This is so that keybindings work. This is good. But some components, like JComboBox, handle their own keybindings and do not want JPopupMenu stealing focus. While we have special cased JComboBox, we need a general solutions for developers that are bumping into this.

EVALUATION Name: pzR10082 Date: 02/05/2002 It appears we can safely use the focusable property of the popup menu. This means, if a popup is not focusable, we will not move focus anywhere when it shows up. For a developer it is sufficient to make their popups non-focusable. ###@###.### 2002-02-05 ======================================================================
