I referred to the original JBS issue for which this test was created - [JDK-4759934](https://bugs.openjdk.org/browse/JDK-4759934). Looks like we can use doClick() instead of using Robot for the clicks.

But the problem is that when we use doClick() for frameBtn and dialogBtn, JFC's click on Cancel button doesn't happen and the test fails due to timeout. This happens on macOS26, I have to test on other platforms.



            SwingUtilities.invokeAndWait(() -> frameBtn.doClick());
            robot.waitForIdle();
            robot.delay(500);

            SwingUtilities.invokeAndWait(() -> dialogBtn.doClick());
            robot.waitForIdle();
            robot.delay(500);

            SwingUtilities.invokeAndWait(() -> {
                JButton cancelBtn = findCancelButton(jfc);
                cancelBtn.doClick();
            });
            robot.delay(500);
