RFR: 8235404: [macos] JOptionPane blocks drawing string on another component [v5]

[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.
