            When the test starts, you will see a Frame with a Button
            titled 'Show modal dialog with delay'. Press this button
            and before the modal Dialog is shown, try to close the
            Frame using X button or system menu for windowing systems
            which don't provide X button in Window decorations. The
            delay before Dialog showing is 5 seconds.
            If in test output you see message about WINDOW_CLOSING
            being dispatched, then test fails. If no such message
            is printed, the test passes.
