Accessibility ComboBox bound to non string object causes Narrator to read class name rather than displayed value

[ahopper]

Describe the bug

If a ComboBox is bound to a list of non string objects the Narrator screen reader will read the class name for the selected object. It correctly reads the displayed value for the items in the list once it is opened.

Expected behavior

Narrator to read the displayed value

Try to override ToString of that bound object

That does make it work (and how I had worked around it), but I'm not sure it is how it should be, it seems odd that the text is read out for the dropdown list and not when the dropdown is closed. I just tested on WPF and it reads the class name for both cases. My feeling is it should use the displayed text, this might be different across multiple uses of the object and you have already defined the text you want with either a template or DisplayBemberBinding. Anything that makes Accessibility automatic seems good to me, but if this is expected behaviour so be it.

@ahopper I am not sure about automation. I feel like there is some room for optimization and your suggestion could be part of it. But in the end the experts needs to decide. I think following what WPF does if applicable would maybe be a good idea.
