[combobox] readonly combobox is not announced as readonly by NVDA

[knoobie]

What is the problem?

At least Firefox + NVDA annouces a readonly combobox with a pre-selected value as editable. (Haven't tested other combination)

    var cb = new ComboBox<String>("Name");
    cb.setItems(List.of("1", "2", "3"));
    cb.setValue("1");
    cb.setReadOnly(true);

NVDA german log with engl. in( )

name_of_field  Kombinationsfeld(combobox)  reduziert(reduced)  erforderlich(required)  mit AutoVervollständigung(autofill)  bearbeitbar(editable)  value_of_field ausgewählt(selected)

Note: Other fields like the TextField work correctly.

Same Problem with

• Select
• DatePicker
• DateTimePicker
• IntegerField
• Checkbox (although I am unsure if this is supposed to work, since HTML doesn't define a readonly checkbox)

and probably more. Tested with Chrome and NVDA in German.
