      Description

      On Mac OS modal dialogs overlapping order is wrong.

      Below a test that demonstrates the wrong behavior is provided (a modified test taken from https://stackoverflow.com/questions/46922555/correct-parent-for-modal-dialog-in-swing).
      Run the test and create 4 consequently modal dialogs using the button. Their appeared overlapping order is
      4 - 1 - 2 - 3
      but the expected order is
      4 - 3 - 2 - 1
