This in turn makes the method dragSourceListener.isDropFinished() returns false and fail the test. To fix this, setAutoWaitForIdle(true) and Thread.Sleep is called to make sure the mouseMove() event is processed completely before moving to execute the mousePress() method.

Both the original test and updated test in this PR pass on the latest macOS version 14.2. Since this is a test stabilization fix I would like to suggest a change to JBS title to reflect it since the current one might be misleading.

These boolean vars need to be volatile since they are accessed on two different threads.
