I see.

I expected to have `waitForIdle` after `await` to ensure all other pending events including `paint` is handled.


            robot.mousePress(InputEvent.BUTTON1_DOWN_MASK);
            latch.await();
            robot.waitForIdle();
            robot.delay(1000);


In this case, it could be possible to reduce the delay… or maybe not.
