Accessibility. Inaccessible shut down virtual machine screen with screen readers enabeled.

When navigating the virtual machine shut down screen with screen reader enabeled, none of the elements can be announced by screen reader. All of the elements are announced as "Unknown". Steps to reproduce:

1. Launch NVDA. You can get it from: ​https://nvaccess.org/
2. Launch virtual box and launch virtual machine in it.
3. When the virtual machine is launched, press right CTRL+q key combination.

You will here: close virtual machine.

4. Tab between elements.

You will here "Unknown". Expected result: Screen reader should announce the element's name, role and value. In this case: Okay and cancel buttons and the set of radiobuttons: "Save the machine state, Send the shutdown signal, Power off the machine". Actual result: Screen reader doesn't announce any elements, it keeps saying "Unknown" while tabbing and moving with up and down arrows between radio buttons, so it is impossible to shut down the virtual machine using the screen reader. See standards and guidelines: ​https://www.w3.org/WAI/WCAG21/Understanding/name-role-value.html

Could you please test launching the vm as "Detachable" either from the start menu of the VirtualBox Manager or through VBoxManage. Please refer to https://www.virtualbox.org/manual/ch08.html#vboxmanage-startvm. Let me know if this alleviates the problem somewhat.

Hello, I have just tryed to run the created VM in the detachable mode and pressed right CTRL+q. In the detachable mode screen reader announces all controls in the shut down virtual machine window. Ok and cancel buttons and all needed radiobuttons in the set of radiobuttons. Thank you!
