Serious incorrect output on role=listbox with aria-readonly=true

[JAWS-test]

Summary

1. Go to https://codepen.io/jaws-test/pen/WNZrREZ
2. Press F5 or C (quick navigation to the listbox)
3. Press INS+F5 (element overview)
4. Press Tab to reach the listbox
5. Read with arrow keys (virtual cursor)

Expected result

List box is output with its readonly state

Actual result

• Form mode: List box is output without its readonly state (Firefox: output as listbox, Chrome: output acoustically as list, on Braille as listbox).
• Reading mode (arrow keys, F5, INS+F5): No output of list box name, role, value and state. The listbox is not available for screen reader users

Notes:

• The problem also occurs with HTML select (see: https://github.com/w3c/html-aria/issues/384)
• The problem that the readonly state is not noticeable in form mode also occurs with NVDA.
• The problem that the element is not present in reading mode does not occur with NVDA
