        On OS X, if you send an event directly to a window, the modal dialog
        doesn't block the event, so the window will process it normally. This
        is a different code path compared to having a user click the mouse and
        generate a native event; in that case the OS does the filtering itself,
        and Qt will not even see the event. But simulating real events in the
        test framework is generally unstable. So there isn't a good way to test
        modality on OS X.
        This test sometimes fails on other platforms too.  Maybe it's not reliable
        to try to click the main window in a location which is outside the
        dialog, without checking or guaranteeing it somehow.
