AFAIK, I don't think that it is a bug because the arrow button in Aqua LAF is an instance of AquaComboBoxButton. So, native side invoked a11y API based on component. Similarly, For non-editable JComboBox, editor is an instance of JTextField and a11y API invoked on NavigableTextAccessibility.

I think this may be a solution to handle custom as well as default renderer.

One of the CI test failed with this fix. Looking into it, will update it accordingly.
