Fix a problem where the WINDOWSET tests would fail during the full test pass. They have always failed on the wxWidgets version because the MINIMIZE/MAXIMIZE/RESTORE tests would revive an editor window that was supposedely closed. This is an result of an intentional design descision of wxWidgets, when a window is destroyed, it is not destroyed immediately, it is destroyed when the application is idle. Since the application is not idle what the tests are running, if the EDITOR tests are run before the WINDOWSET tests, there would be a window named "Editor" that would conflict with the window that it created for testing.
