RFR: 8235404: [macos] JOptionPane blocks drawing string on another component

[Alisen Chung]

Currently if you try to use graphics to draw a string on a frame using JOptionPane + JTextField with a listener as a prompt, the string will not draw. Adding a repaint after dialog.dispose in JOptionPane will cause the text to show after the dialog is closed.
