Test to reproduce bugs
======================
1. On macOS, start VoiceOver (for example with shortcut Option-Command-F5).

2. Start SwingSet2.jar with jdk-21 (or idk-20, which behaves the same).
-> SwingSet2 window is displayed. The ToggleButton “JInternalFrame demo” has the keyboard focus.

3. Press F10 to open the menu of the SwingSet2 application.
-> The "File" menu is selected and expanded.
-> VoiceOver announces: "menu (5 items). You are currently in a menu."

4. Press Right Arrow key.
-> The "Look & Feel" menu is selected and expanded.
-> VoiceOver announces: "menu (4 items). You are currently in a menu."

5. Press Down Arrow key.
-> The "Java Look & Feel" radio button menu item is selected.
Bug: VoiceOver does not announce anything.

6. Press Down Arrow key.
-> The "Nimbus Look & Feel" radio button menu item is selected.
Same bug as mentioned before.

7. Press Right Arrow key twice.
-> The "Options" menu is selected and expanded.
-> VoiceOver announces: "menu (2 items). You are currently in a menu."

8. Press Down Arrow key.
-> The "Enable Tool Tips" checkbox menu item is selected.
Same bug as mentioned above.

9. Press Down Arrow key.
-> The "Enable Drag Support" checkbox menu item is selected.
Same bug as mentioned above.


Note: Mentioning a bug on VoiceOver announcement does not mean that the issue is on VoiceOver’s side, rather it is the result of the issue and the cause of the issue needs to be found.
